+
+### Technology Stack
+
+| Component | Library/Tool | Purpose |
+|-----------|-------------|---------|
+| **Network Protocol** | WebRTC | Real-time browser communication |
+| **Audio Codec** | Opus | High-quality low-bitrate encoding |
+| **Streaming Framework** | GStreamer | Multimedia pipeline management |
+| **Python Bridge** | PyGObject (GI) | GStreamer ↔ Python/NumPy |
+| **Signaling** | aiohttp + WebSockets | WebRTC session negotiation |
+| **NAT Traversal** | STUN/TURN (coturn) | Firewall penetration |
+| **Orchestration** | Kubernetes | Auto-scaling, load balancing |
+| **Monitoring** | Prometheus/Grafana | Metrics, alerting |
+| **Model** | PyTorch (unchanged) | Deep learning inference |
+
+### Strengths ✅
+
+1. **Cloud-native** - Runs anywhere (AWS, GCP, Azure)
+2. **Horizontally scalable** - Auto-scale from 3 to 100+ pods
+3. **Low bandwidth** - 64kbps vs 320kbps = **80% reduction**
+4. **Browser-compatible** - Works on any modern browser
+5. **Adaptive quality** - Opus adjusts to network conditions
+6. **Encrypted** - DTLS-SRTP built-in
+7. **Global reach** - Deploy to multiple regions
+8. **Hardware acceleration** - GPU encoding (NVENC)
+9. **Production-ready** - Battle-tested protocols (WebRTC used by Zoom, Teams)
+10. **Observable** - Prometheus metrics for latency, quality, errors
+
+### Trade-offs ⚠️
+
+1. **Network latency added** - +50-150ms depending on client location
+2. **More complex setup** - Requires GStreamer, WebRTC signaling server
+3. **Internet required** - Cannot work offline
+4. **TURN server costs** - ~$0.05/GB for relay traffic (only if direct P2P fails)
+
+---
+
+## Latency Breakdown Comparison
+
+### Current (Local Desktop)
+
+| Stage | Time | Notes |
+|-------|------|-------|
+| Mic capture buffer | 20ms | sounddevice default |
+| Input queue | 30ms | Python threading |
+| **Processing** | **300ms** | Seed-VC algorithm |
+| Output queue | 30ms | Python threading |
+| Speaker playback buffer | 50ms | sounddevice default |
+| **TOTAL** | **430ms** | ✅ Good for local use |
+
+### GStreamer Cloud (Best Case - Client in same region)
+
+| Stage | Time | Notes |
+|-------|------|-------|
+| Mic capture (browser) | 20ms | WebRTC default |
+| Client encoding (Opus) | 10ms | Browser native |
+| Network uplink | 30ms | Same region |
+| Jitter buffer | 30ms | GStreamer adaptive |
+| Decode + resample | 5ms | GStreamer |
+| **Processing** | **300ms** | Seed-VC algorithm (same) |
+| Resample + encode | 10ms | GStreamer |
+| Network downlink | 30ms | Same region |
+| Client decoding | 5ms | Browser native |
+| Playback buffer | 20ms | WebRTC default |
+| **TOTAL** | **460ms** | ✅ Acceptable (<500ms) |
+
+### GStreamer Cloud (Worst Case - Cross-continent)
+
+| Stage | Time | Notes |
+|-------|------|-------|
+| Mic → Network | 30ms | Same as above |
+| Network uplink | 150ms | US ↔ Europe |
+| Jitter buffer | 50ms | Higher for stability |
+| Decode + Processing | 315ms | Same pipeline |
+| Encode + Network downlink | 160ms | US ↔ Europe |
+| Network → Playback | 25ms | Same as above |
+| **TOTAL** | **730ms** | ⚠️ Noticeable but usable |
+
+**Solution for high latency:** Deploy regionally (US-East, US-West, EU, Asia)
+
+---
+
+## Scalability Comparison
+
+### Current Architecture
+
+| Metric | Value | Limitation |
+|--------|-------|------------|
+| Concurrent users | 1 | Single desktop app |
+| Scaling method | ❌ None | Cannot scale |
+| Geographic reach | Local only | Desktop-bound |
+| Availability | ~95% | Desktop uptime |
+| Cost model | Free (local) | User's hardware |
+
+### GStreamer Cloud Architecture
+
+| Metric | Value | Method |
+|--------|-------|--------|
+| Concurrent users | 10-1000+ | Horizontal pod scaling |
+| Users per GPU | 10-15 | 300ms/30ms = 10 streams |
+| Scaling method | ✅ Automatic | Kubernetes HPA |
+| Geographic reach | Global | Multi-region deployment |
+| Availability | 99.9% | Kubernetes self-healing |
+| Cost model | $0.50-$2/hour per GPU | Cloud provider pricing |
+
+**Example Scaling:**
+- 1 GPU (T4): 10 concurrent users → $0.50/hour = **$0.05/user/hour**
+- 100 users: 10 GPUs → $5/hour = **$360/month**
+- 1000 users: 100 GPUs → $50/hour = **$36,000/month** (at peak)
+
+With auto-scaling:
+- Off-peak (10 users): 1 GPU = $0.50/hour
+- Peak (1000 users): 100 GPUs = $50/hour
+- Average utilization 20%: **$7,200/month** for 1000 peak users
+
+---
+
+## Bandwidth Comparison
+
+### Current Architecture (File/MP3 Streaming)
+
+```
+1 user, 1 hour session:
+ • Input: Local mic (no bandwidth)
+ • Output: MP3 @ 320kbps = 144 MB/hour
+
+1000 users, 1 hour:
+ • Total egress: 144 GB
+ • AWS CloudFront cost: $85/hour
+```
+
+### GStreamer Cloud (Opus WebRTC)
+
+```
+1 user, 1 hour session:
+ • Input: Opus @ 64kbps = 28.8 MB/hour
+ • Output: Opus @ 64kbps = 28.8 MB/hour
+ • Total: 57.6 MB/hour (60% reduction from MP3 output alone)
+
+1000 users, 1 hour:
+ • Total egress: 28.8 GB (output only, input is to server)
+ • AWS CloudFront cost: $17/hour
+
+Savings: $68/hour = $50,000/month at 1000 concurrent users
+```
+
+**Additional bandwidth optimization:**
+- Variable bitrate (VBR): Opus can go as low as 32kbps for speech
+- Silence detection: Send comfort noise packets (save 50% during pauses)
+
+---
+
+## Development Complexity Comparison
+
+### Current Architecture
+
+**Lines of Code:**
+- `real-time-gui.py`: 1,400 lines
+- `seed_vc_wrapper.py`: 600 lines
+- **Total:** ~2,000 lines (single-user app)
+
+**Dependencies:**
+- PyTorch, librosa, sounddevice
+- FreeSimpleGUI (desktop UI)
+
+**Deployment:**
+- User downloads and runs locally
+- No server infrastructure needed
+
+### GStreamer Cloud Architecture
+
+**Lines of Code:**
+- All current code: ~2,000 lines (reused)
+- `gstreamer_bridge.py`: ~400 lines (new)
+- `webrtc_server.py`: ~600 lines (new)
+- `k8s/deployment.yaml`: ~200 lines (new)
+- HTML client: ~150 lines (new)
+- **Total:** ~3,350 lines (+67% code)
+
+**Dependencies:**
+- All current + GStreamer + PyGObject
+- aiohttp, aiortc (WebRTC)
+- Kubernetes, Docker
+- TURN server (coturn)
+
+**Deployment:**
+- Docker image build
+- Kubernetes cluster setup
+- Domain + SSL certificate
+- TURN server configuration
+- Monitoring setup (Prometheus/Grafana)
+
+**Complexity Assessment:**
+- Initial setup: 2-3 weeks (vs. 0 for local)
+- Maintenance: Moderate (monitoring, updates)
+- **Value:** Unlocks cloud deployment, scalability, global reach
+
+---
+
+## Cost Analysis (AWS Example)
+
+### Current Architecture (Local Desktop)
+
+**User Cost:**
+- Hardware: User's desktop/laptop
+- GPU: Optional (CPU works, slower)
+- Internet: Not required
+- **Total: $0/month** (runs on user's machine)
+
+### GStreamer Cloud Architecture
+
+**Infrastructure Costs (AWS, 1000 peak concurrent users, 20% average):**
+
+| Resource | Spec | Quantity | Unit Cost | Monthly Cost |
+|----------|------|----------|-----------|--------------|
+| GPU instances | g4dn.xlarge (T4) | 100 peak, 20 avg | $0.526/hour | $7,862 |
+| Load balancer | ALB | 1 | $16.20 + data | $50 |
+| TURN server | t3.medium | 2 (HA) | $0.0416/hour | $60 |
+| Storage (S3) | Reference voices | 100 GB | $0.023/GB | $2.30 |
+| Bandwidth | CloudFront egress | 28.8 TB (1000 users) | $0.085/GB | $2,448 |
+| Monitoring | Prometheus/Grafana | Managed | - | $50 |
+| **TOTAL** | | | | **$10,472/month** |
+
+**Per-user cost at 20% utilization:**
+- $10,472 / 200 average users = **$52.36/user/month**
+
+**Revenue Model Options:**
+1. Subscription: $9.99/user/month (need 1,048 users to break even)
+2. Pay-as-you-go: $0.10/minute = $6/hour (2M minutes/month to break even)
+3. Freemium: Free tier + premium features
+
+---
+
+## Migration Strategy
+

+- ⏭️ GPU encoding (NVENC)
+- ⏭️ Batch processing (multiple streams)
+- ⏭️ Edge caching (CloudFront)
+
+---
+
+## Recommendation
+
+### ✅ Proceed with GStreamer Integration
+
+**Primary Reasons:**
+1. **Enables cloud deployment** - Essential for SaaS business model
+2. **80% bandwidth reduction** - Significant cost savings at scale
+3. **Industry-standard technology** - WebRTC is proven and widely supported
+4. **Scalability** - From 1 user to millions
+5. **Global reach** - Deploy to multiple regions
+
+**Timeline:** 10 weeks to production-ready cloud service
+
+**ROI Threshold:** ~1,000 paying users to cover infrastructure costs
+
+**Risk Level:** **Medium** (proven technology, but requires expertise)
+
+---
+
+## Conclusion
+
+The GStreamer-enhanced architecture transforms Seed-VC from a **desktop application** into a **cloud-native real-time service**. While it adds complexity, the benefits of scalability, reduced bandwidth, and global deployment make it essential for commercial success.
+
+**Next Step:** Begin Phase 1 (Proof of Concept) following the implementation guide.

+
+### Data Flow
+
+**WebRTC Flow (via Janus):**
+```
+Browser → Janus (WebRTC) → RTP → Seed-VC → RTP → Janus (WebRTC) → Browser
+```
+
+**Direct RTP Flow:**
+```
+Client → RTP (port 5004) → Seed-VC → RTP (port 5005) → Client
+```
+
+**HTTP API Flow:**
+```
+Client → HTTP POST /convert → Seed-VC → HTTP Response (WAV) → Client
+```
+
+---
+
+## Deployment Options
+
+### Option 1: RTP Mode (Default)
+
+Best for: Direct RTP streaming, testing, controlled environments
+
+```bash
+docker-compose up -d
+```
+
+This starts:
+- Janus Gateway (ports 8088, 10000-10200/udp)
+- Seed-VC RTP server (ports 5004/5005 udp)
+
+### Option 2: HTTP API Mode
+
+Best for: File-based conversion, REST API integration
+
+```bash
+docker-compose --profile http-mode up -d
+```
+
+This starts:
+- Seed-VC HTTP server (port 8080)
+
+**Usage:**
+```bash
+# Convert voice via HTTP API
+curl -X POST http://localhost:8080/convert \
+ -F "source=@source.wav" \
+ -F "reference=@reference.wav" \
+ -F "diffusion_steps=10" \
+ -o output.wav
+
+# Health check
+curl http://localhost:8080/health
+```
+
+### Option 3: Production Mode (with Nginx)
+
+Best for: Production deployment, SSL termination, load balancing
+
+```bash
+docker-compose --profile production up -d
+```
+
+This starts:
+- All services
+- Nginx reverse proxy (ports 80, 443)
+- TURN server (coturn)
+

+
+## Janus Integration
+
+### Why Janus Gateway?
+
+**Janus Gateway** is a production-ready, open-source WebRTC server that handles:
+- ✅ WebRTC signaling (SDP offer/answer, ICE candidates)
+- ✅ Multiple protocols (HTTP, WebSocket, MQTT, RabbitMQ)
+- ✅ NAT traversal (STUN/TURN integration)
+- ✅ Recording and playback
+- ✅ Clustering for horizontal scaling
+- ✅ Plugin system for custom logic
+
+**Advantages over custom WebRTC implementation:**
+- Battle-tested in production (used by major telecom companies)

+
+
+ Ready
+
+
+
+
+```
+
+### Janus Configuration
+
+To use Janus with Seed-VC, you need to configure the streaming plugin to forward RTP to/from Seed-VC.
+
+**Create `janus-config/janus.plugin.streaming.jcfg`:**
+
+```ini
+general: {
+ events = false
+ json = "compact"
+}
+
+# Seed-VC Voice Conversion Stream
+seedvc-stream: {
+ type = "rtp"
+ id = 1
+ description = "Seed-VC Voice Conversion"
+ audio = true
+ audioport = 5004 # Send to Seed-VC
+ audiopt = 111
+ audiocodec = "opus"
+ audiofmtp = "useinbandfec=1"
+
+ # Receive converted audio from Seed-VC
+ audioport_out = 5005
+
+ # RTP settings
+ videoskew = true
+ audioskew = true
+}
+```
+
+**Note:** Janus Gateway configuration can be complex. For production use, consider:
+1. Using the official Janus documentation: https://janus.conf.meetecho.com/docs/
+2. Exploring Janus Docker images with pre-configured settings
+3. Using managed Janus services
+
+---
+
+## Configuration
+
+### Environment Variables
+
+**docker-compose.yml** supports these environment variables:
+
+```bash
+# Create .env file
+cat > .env << EOF
+# Docker network configuration
+DOCKER_IP=auto
+
+# Seed-VC configuration
+REFERENCE_VOICE=/app/data/reference.wav
+DIFFUSION_STEPS=10
+
+# GPU configuration
+NVIDIA_VISIBLE_DEVICES=all
+
+# Ports
+RTP_INPUT_PORT=5004
+RTP_OUTPUT_PORT=5005
+HTTP_PORT=8080
+JANUS_WS_PORT=8088
+EOF
+```
+
+### Volume Mounts
+
+- `./data:/app/data` - Reference voice files
+- `./models:/app/models` - Cached model weights (persists across restarts)
+- `./output:/app/output` - Output files
+- `./janus-recordings:/opt/janus/share/janus/recordings` - Janus recordings
+
+### Resource Limits
+
+Edit `docker-compose.yml` to adjust GPU/memory limits:
+
+```yaml
+services:
+ seedvc-rtp:
+ deploy:
+ resources:
+ limits:
+ memory: 8G
+ reservations:
+ devices:
+ - driver: nvidia
+ count: 1 # Number of GPUs
+ capabilities: [gpu]
+```
+
+---
+
+## Scaling
+
+### Horizontal Scaling with Multiple Containers
+
+```bash
+# Scale Seed-VC containers
+docker-compose up -d --scale seedvc-rtp=3
+
+# Use a load balancer (e.g., Nginx) to distribute RTP streams
+```
+
+### Kubernetes Deployment
+
+See separate `k8s/` directory for Kubernetes manifests:
+
+```bash
+# Deploy to Kubernetes
+kubectl apply -f k8s/namespace.yaml
+kubectl apply -f k8s/deployment.yaml
+kubectl apply -f k8s/service.yaml
+kubectl apply -f k8s/hpa.yaml # Horizontal Pod Autoscaler
+```
+
+### Multi-GPU Support
+
+```yaml
+# docker-compose.yml
+seedvc-rtp-gpu0:
+ <<: *seedvc-rtp
+ environment:
+ - NVIDIA_VISIBLE_DEVICES=0
+ ports:
+ - "5004:5004/udp"
+ - "5005:5005/udp"
+
+seedvc-rtp-gpu1:
+ <<: *seedvc-rtp
+ environment:
+ - NVIDIA_VISIBLE_DEVICES=1
+ ports:
+ - "5006:5004/udp"
+ - "5007:5005/udp"
+```
+
+---
+
+## Troubleshooting
+
+### Container won't start
+
+```bash
+# Check logs
+docker-compose logs seedvc-rtp
+
+# Common issues:
+# 1. GPU not available
+docker run --rm --gpus all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
+
+# 2. Port conflicts
+sudo netstat -tulpn | grep 5004
+
+# 3. Out of memory
+docker stats
+```
+
+### No audio output
+
+```bash
+# Verify GStreamer inside container
+docker-compose exec seedvc-rtp gst-inspect-1.0 opusenc
+
+# Test RTP connectivity
+docker-compose exec seedvc-rtp nc -u -l 5004 # Listen
+# In another terminal:
+echo "test" | nc -u localhost 5004 # Send
+```
+
+### Janus connection fails
+
+```bash
+# Check Janus is running
+curl http://localhost:8088/janus/info
+
+# Check WebSocket
+websocat ws://localhost:8088/janus
+```
+
+### GPU not detected
+
+```bash
+# Check NVIDIA driver
+nvidia-smi
+
+# Check Docker can access GPU
+docker run --rm --gpus all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
+
+# Rebuild with GPU support
+docker-compose build --no-cache
+```
+
+### High latency
+
+1. Reduce diffusion steps: Edit `server.py` and change `diffusion_steps=10` to `diffusion_steps=4`
+2. Adjust jitter buffer: Lower `latency` in GStreamer pipelines
+3. Use faster GPU: T4 → A10 → A100
+
+---

+# Executive Summary: GStreamer Integration for Seed-VC
+## Cloud-Based Real-Time Voice Conversion
+
+**Prepared:** 2025-11-16
+**Project:** Seed-VC Zero-Shot Voice Conversion
+**Objective:** Enable cloud deployment for real-time voice conversion at scale
+
+---
+
+## Overview
+
+This document summarizes the analysis and recommendations for integrating GStreamer into the Seed-VC voice conversion framework to enable cloud-based, real-time voice conversion services.
+
+### Current State
+
+**Seed-VC** is a high-quality zero-shot voice conversion system that can:
+- Clone any voice from 1-30 seconds of reference audio
+- Perform real-time conversion with ~430ms latency (local desktop)
+- Support singing voice conversion at 44.1kHz
+- Fine-tune on custom speakers with minimal data
+
+**Current Limitations for Cloud Deployment:**
+- ❌ Uses `sounddevice` (local audio devices only)
+- ❌ No network streaming protocols
+- ❌ File-based I/O (not suitable for streaming)
+- ❌ High bandwidth (MP3 @ 320kbps)
+- ❌ Cannot scale horizontally
+- ❌ Single-user desktop application
+
+---
+
+## Recommendation
+
+### ✅ **PROCEED with GStreamer Integration**
+
+**Primary Benefits:**
+1. **Enables cloud deployment** - Essential for SaaS business model
+2. **80% bandwidth reduction** - Opus (64kbps) vs MP3 (320kbps)
+3. **Industry-standard** - WebRTC used by Zoom, Teams, Discord
+4. **Horizontally scalable** - Support 1 to 10,000+ concurrent users
+5. **Global reach** - Deploy to multiple cloud regions
+6. **Cost-effective** - $52/user/month at scale (1000 users)
+
+**Key Metrics:**
+
+| Metric | Current | With GStreamer | Change |
+|--------|---------|----------------|--------|
+| **Latency** | 430ms (local) | 460-730ms (cloud) | +30-300ms |
+| **Bandwidth** | 320 kbps | 64 kbps | **-80%** |
+| **Scalability** | 1 user | 10,000+ users | **∞** |
+| **Deployment** | Local desktop | Global cloud | ✅ |
+| **Cost/user** | $0 (user's HW) | $52/month | Infrastructure |
+| **Algorithm** | 300ms | 300ms | **Unchanged** |
+
+---
+
+## Technical Approach
+
+### Architecture Overview
+
+```
+Browser (WebRTC) ─┬─> GStreamer Input ──> Seed-VC Processing ──> GStreamer Output ─┬─> Browser
+ │ • Opus decode • DiT model │
+ │ • Resample • BigVGAN │
+ │ • Jitter buffer • 300ms latency │
+ │ • appsink │

+
+---
+
+## Cost Analysis
+
+### Infrastructure Costs (AWS Example)
+
+**Scenario:** 1,000 peak concurrent users, 20% average utilization
+
+| Resource | Monthly Cost | Notes |
+|----------|--------------|-------|
+| GPU instances (g4dn.xlarge) | $7,862 | 100 peak, 20 avg = 20 instances |
+| Load balancer (ALB) | $50 | WebSocket routing |
+| TURN server (2x t3.medium) | $60 | NAT traversal (HA) |
+| Storage (S3) | $2.30 | 100GB reference voices |
+| Bandwidth (CloudFront) | $2,448 | 28.8TB @ $0.085/GB |
+| Monitoring | $50 | Prometheus/Grafana |
+| **TOTAL** | **$10,472/month** | **$52.36/user/month** |
+
+### Revenue Model Options
+
+**Option 1: Subscription**
+- Price: $9.99/user/month
+- Break-even: 1,048 paid users
+- Margin at 2,000 users: $9,508/month (47.6%)
+
+**Option 2: Pay-as-you-go**
+- Price: $0.10/minute ($6/hour)
+- Break-even: 2M minutes/month (33,333 user-hours)
+- Better for occasional users
+
+**Option 3: Freemium**
+- Free tier: 10 minutes/month per user
+- Premium: $19.99/month for unlimited
+- Conversion rate target: 5%
+
+### Bandwidth Cost Savings
+
+**Before (MP3 @ 320kbps):**
+- 1,000 users × 1 hour = 144 GB egress
+- AWS CloudFront: $85/hour
+- Annual cost: $745,200 (24/7 operation)
+
+**After (Opus @ 64kbps):**
+- 1,000 users × 1 hour = 28.8 GB egress
+- AWS CloudFront: $17/hour
+- Annual cost: $148,920
+- **Savings: $596,280/year (80%)**
+
+---
+
+## Performance Analysis
+
+### Latency Budget
+
+**Best Case (Client in same region):**
+```
+Client capture: 20ms
+Client encoding: 10ms
+Network uplink: 30ms ← Added by cloud
+Jitter buffer: 30ms ← Added by cloud
+Decode + resample: 5ms ← Added by cloud
+─────────────────────────
+SEED-VC PROCESSING: 300ms (Unchanged)
+─────────────────────────
+Resample + encode: 10ms ← Added by cloud
+Network downlink: 30ms ← Added by cloud
+Client decoding: 5ms
+Client playback: 20ms
+═════════════════════════
+TOTAL: 460ms ✅ Acceptable (<500ms)
+```
+
+**Worst Case (Cross-continent):**
+- Network RTT: 150ms (vs 30ms)
+- Jitter buffer: 50ms (vs 30ms)
+- **Total: 730ms** ⚠️ Noticeable but usable
+
+**Solution:** Deploy to multiple regions (US, EU, Asia)
+
+### Scalability
+
+**Per-GPU Capacity:**
+- Algorithm latency: 300ms per stream
+- Block time: 180ms (chunk processing)
+- Theoretical max: 300ms / 30ms = **10 streams per GPU**
+- Practical limit: **8 streams** (20% safety margin)
+
+**Horizontal Scaling:**
+- Kubernetes HPA (Horizontal Pod Autoscaler)
+- Min replicas: 3 (HA)
+- Max replicas: 100+ (cost-dependent)
+- Scale trigger: GPU utilization > 80%
+
+**Example Scale-up:**
+```
+Users: 10 → 100 → 1,000 → 10,000
+GPUs: 2 → 13 → 125 → 1,250
+Cost/hr: $1 → $6.8 → $65.7 → $657
+```

+
+## Conclusion
+
+GStreamer integration is **essential and recommended** for transforming Seed-VC into a cloud-native, scalable voice conversion service. The technology is proven, the implementation is well-defined, and the business case is compelling.
+
+**Key Takeaway:**
+> With a 10-week engineering effort, Seed-VC can evolve from a desktop app to a global, scalable SaaS platform capable of serving 10,000+ concurrent users with <600ms latency and 80% lower bandwidth costs.
+
+**Risk Level:** Medium
+**ROI Potential:** High (if 1,000+ users acquired)
+**Strategic Value:** Essential for commercial viability

+Quick start:
+
+1. Install additional dependencies:
+```bash
+pip install aiohttp aiortc
+```
+
+2. Create signaling server (see analysis doc)
+3. Create HTML client (see analysis doc)
+4. Run server:
+```bash
+python server/webrtc_server.py
+```
+
+5. Open browser to `http://localhost:8080`
+
+---
+
+## Performance Optimization Tips
+
+### 1. Reduce Diffusion Steps for Real-Time
+
+```python
+# Quality vs. Speed trade-off
+diffusion_steps = 10 # Real-time (150ms)
+# vs.
+diffusion_steps = 25 # High quality (350ms)
+```
+
+### 2. Use Model Compilation
+
+```python
+# In seed_vc_wrapper.py __init__
+import torch._dynamo
+torch._dynamo.config.suppress_errors = True
+
+# Compile model for faster inference
+self.model.cfm.estimator = torch.compile(
+ self.model.cfm.estimator,
+ mode='reduce-overhead'
+)
+```
+
+### 3. Batch Processing
+
+Process multiple streams in parallel:
+
+```python
+# Process 4 streams simultaneously
+batch_size = 4
+source_chunks = [stream1, stream2, stream3, stream4]
+source_batch = torch.stack(source_chunks)
+# Process batch together (4x throughput)
+```
+
+### 4. Hardware Encoding (NVIDIA GPU)
+
+```python
+# In GStreamer output pipeline, replace opusenc with nvopusenc
+pipeline_str = """
+ appsrc ! ... !
+ nvopusenc ! rtpopuspay ! udpsink
+"""
+```
+
+---
+
+## Troubleshooting
+
+### Issue: "No module named 'gi'"
+
+**Solution:**
+```bash
+pip install PyGObject
+# If fails, install system dependencies first:
+sudo apt-get install libgirepository1.0-dev gcc libcairo2-dev pkg-config python3-dev gir1.2-gtk-3.0
+```
+
+### Issue: "Could not find element 'opusenc'"
+
+**Solution:**
+```bash
+sudo apt-get install gstreamer1.0-plugins-bad
+gst-inspect-1.0 opusenc # Verify
+```
+
+### Issue: High latency / Audio dropouts
+
+**Solutions:**
+1. Reduce jitter buffer: `rtpjitterbuffer latency=20`
+2. Increase buffer size: `appsink max-buffers=20`
+3. Use faster GPU
+4. Reduce diffusion steps
+
+### Issue: Pipeline errors "Could not link elements"
+
+**Solution:**
+Add `audioconvert ! audioresample !` between incompatible elements
+
+---
+
+## Next Steps
+
+1. ✅ Complete basic file-based testing
+2. ✅ Test RTP streaming locally
+3. ⏭️ Implement WebRTC signaling server
+4. ⏭️ Deploy to cloud (Docker + Kubernetes)
+5. ⏭️ Load testing and optimization
+6. ⏭️ Add monitoring (Prometheus metrics)

+# GStreamer Integration Analysis for Seed-VC
+## Real-Time Cloud Voice Conversion
+
+**Date:** 2025-11-16
+**Project:** Seed-VC Zero-Shot Voice Conversion
+**Goal:** Cloud-hosted real-time voice conversion using GStreamer
+
+---
+
+## Executive Summary
+
+This document provides a comprehensive analysis of integrating GStreamer into the Seed-VC voice conversion framework to enable efficient, low-latency cloud deployment. GStreamer would replace the current file-based and sounddevice I/O with network-capable streaming pipelines suitable for production cloud services.
+
+**Key Findings:**
+- ✅ **HIGHLY RECOMMENDED** - GStreamer is an excellent fit for this use case
+- 🎯 **Current Latency:** ~430ms (300ms algorithm + 130ms device I/O)
+- 🎯 **Target Latency:** <500ms end-to-end with network streaming
+- 📊 **Processing:** Already chunked (180ms blocks) - ideal for streaming
+- 🚀 **Benefits:** WebRTC, RTP streaming, hardware acceleration, adaptive bitrate
+
+---
+
+## Current Architecture Analysis
+
+### Audio Processing Pipeline
+
+```
+Current Local Processing:
+┌──────────────────────────────────────────────────────────────┐
+│ INPUT (sounddevice/librosa) │
+│ ↓ │
+│ 180ms audio chunks @ 22050 Hz │
+│ ↓ │
+│ Feature Extraction (Whisper @ 16kHz) │
+│ ↓ │
+│ DiT Model Inference (~150ms/chunk) │
+│ ↓ │
+│ BigVGAN Vocoding │
+│ ↓ │
+│ Overlap-Add (16 frames cosine fade) │
+│ ↓ │
+│ OUTPUT (sounddevice/MP3 file) │
+└──────────────────────────────────────────────────────────────┘
+```
+
+### Current Audio Stack
+
+| Component | Library | Purpose | Cloud-Ready? |
+|-----------|---------|---------|--------------|
+| **File I/O** | librosa, soundfile | Load WAV/MP3 | ❌ File-based |
+| **Device I/O** | sounddevice | Mic/speaker access | ❌ Local only |
+| **Resampling** | torchaudio | 16kHz/22kHz conversion | ✅ Yes |
+| **Mel-spec** | torch STFT | Feature extraction | ✅ Yes |
+| **Streaming** | pydub MP3 | Web delivery | ⚠️ Limited |
+| **Protocol** | None | Network streaming | ❌ Missing |
+
+### Identified Gaps for Cloud Deployment
+
+1. ❌ **No network streaming protocols** (RTP, RTSP, WebRTC)
+2. ❌ **No adaptive bitrate streaming** (HLS, DASH)
+3. ❌ **Limited codec support** (only WAV/MP3 via pydub)
+4. ❌ **No jitter buffering** for network conditions
+5. ❌ **No hardware encoding** (GPU encoding for opus/aac)
+6. ⚠️ **File-based workflow** (not optimized for streams)
+
+---
+
+## GStreamer Integration Proposal
+
+### Why GStreamer?
+
+GStreamer is the **industry standard** for multimedia streaming and is used by:
+- **Google**: WebRTC, Chrome media stack
+- **Microsoft**: Teams, Azure Media Services
+- **Amazon**: AWS Kinesis Video Streams
+- **Twitch, Discord, Zoom**: Real-time communications
+
+### Key Benefits for Seed-VC
+
+#### 1. **Network Streaming Protocols**
+```
+Client Browser/App ←→ Cloud Seed-VC Server
+ │ │
+ │ WebRTC (OPUS) │
+ │ ◄──────────────────► │
+ │ │
+ Low latency (<200ms network) │
+```
+
+**Supported Protocols:**
+- **WebRTC**: Browser-native, P2P capable, <200ms latency
+- **RTP/RTSP**: Standard streaming, NAT-friendly
+- **SRT**: Secure reliable transport, sub-second latency
+- **RTMP**: Compatible with streaming platforms
+- **HLS/DASH**: Adaptive bitrate for varying bandwidth
+
+#### 2. **Advanced Audio Codecs**
+
+| Codec | Bitrate | Latency | Quality | Use Case |
+|-------|---------|---------|---------|----------|
+| **Opus** | 32-128 kbps | 5-60ms | Excellent | **RECOMMENDED** for real-time |
+| AAC-LC | 128-256 kbps | 50-100ms | High | Broadcast quality |
+| G.722 | 64 kbps | <10ms | Good | VoIP compatible |
+| Vorbis | 96-256 kbps | 50ms | High | Open-source |
+
+**Current:** MP3 @ 320kbps = **10x more bandwidth than Opus at same quality**
+
+#### 3. **Hardware Acceleration**
+
+```python
+# CPU Encoding (current)
+pydub.export(format="mp3", bitrate="320k") # ~50ms CPU encoding
+
+# GPU Encoding (GStreamer + NVENC)
+nvopusenc bitrate=64000 # ~2ms GPU encoding
+```
+
+**Available Hardware Encoders:**
+- NVIDIA NVENC (H.264, HEVC, AV1)
+- Intel Quick Sync (QSV)
+- AMD VCE
+- Apple VideoToolbox (M-series)
+
+#### 4. **Adaptive Jitter Buffering**
+
+GStreamer automatically handles:
+- Network jitter compensation
+- Packet loss recovery (with FEC)
+- Clock synchronization (NTP)
+- Out-of-order packet reordering
+
+#### 5. **Plugin Ecosystem**
+
+1,400+ plugins including:
+- **Audio processing**: Equalizer, compressor, noise gate
+- **Effects**: Reverb, pitch shift (could replace RMVPE preprocessing)
+- **Analytics**: Loudness metering, VAD
+- **Integration**: WebRTC, SIP, RTMP ingest/egress

+
+**End-to-End Latency Budget:**
+
+| Stage | Current | With GStreamer | Notes |
+|-------|---------|----------------|-------|
+| Capture buffer | 20ms | 20ms | Client-side |
+| Network uplink | N/A | 30-100ms | Varies by location |

+| Device I/O | 130ms | 0ms | Eliminated |
+| Encode + resample | N/A | 10ms | GStreamer |
+| Network downlink | N/A | 30-100ms | Varies by location |
+| Playback buffer | 20ms | 20ms | Client-side |

+
+## Alternative Approaches
+
+### Option 1: WebRTC via aiortc (Python-only)
+
+**Pros:**
+- Pure Python, no GStreamer dependency
+- Easier to integrate initially
+
+**Cons:**
+- Much slower codec performance (no hardware acceleration)
+- Higher CPU usage
+- Limited protocol support
+- Less production-ready
+
+**Verdict:** ❌ Not recommended for production scale
+
+### Option 2: Hybrid Approach (GStreamer for I/O, current code for processing)
+
+**Architecture:**
+```
+GStreamer (network I/O) → Python NumPy → Seed-VC → NumPy → GStreamer (network I/O)
+```
+
+**Pros:**
+- ✅ Minimal code changes to Seed-VC
+- ✅ All benefits of GStreamer networking
+- ✅ Easiest migration path
+
+**Cons:**
+- Cannot leverage GStreamer audio processing plugins
+
+**Verdict:** ✅ **RECOMMENDED** as starting point
+
+### Option 3: Full GStreamer Pipeline (including ML inference)
+
+Use GStreamer ML plugins (gst-inference) to run PyTorch models directly in pipeline.
+
+**Pros:**
+- Fully optimized pipeline
+- No Python overhead
+
+**Cons:**
+- Requires porting Seed-VC to TensorRT/ONNX
+- Complex integration
+- Less flexibility for research
+
+**Verdict:** ⚠️ Future optimization, not initial implementation
+

+
+## Performance Predictions
+
+### Bandwidth Comparison
+
+| Scenario | Current (MP3) | With Opus | Savings |
+|----------|---------------|-----------|---------|
+| 1 minute | 2.4 MB | 0.48 MB | **80%** |
+| 1 hour | 144 MB | 28.8 MB | **80%** |
+| 1000 users | 144 GB/hour | 28.8 GB/hour | **115 GB/hour** |
+
+**Cost Impact (AWS CloudFront):**
+- Current: $144/hour for 1000 concurrent users
+- With Opus: $28.80/hour

+| Playback | 50ms | 20ms |
+| **Total I/O** | **200ms** | **115-215ms** |
+
+**End-to-End (including 300ms algorithm):**
+- Local (current): 500ms
+- Cloud (GStreamer): 415-515ms ✅ **Acceptable**
+
+---
+
+## Risk Assessment
+
+| Risk | Probability | Impact | Mitigation |
+|------|-------------|--------|------------|
+| GStreamer learning curve | High | Medium | Start with simple RTP, add WebRTC later |
+| Python-GStreamer integration bugs | Medium | Medium | Use appsink/appsrc, well-documented |
+| Network jitter affects quality | Medium | High | Use adaptive jitter buffer, FEC |
+| GPU memory constraints | Low | High | Batch size=1, model pruning |
+| Scaling complexity | Medium | Medium | Use Kubernetes HPA, load balancing |
+

+
+---
+
+## Installation
+
+### 1. Install GStreamer (System Packages)
+
+**Ubuntu/Debian:**
+```bash
+sudo apt-get update
+sudo apt-get install -y \
+ gstreamer1.0-tools \
+ gstreamer1.0-plugins-base \
+ gstreamer1.0-plugins-good \
+ gstreamer1.0-plugins-bad \
+ gstreamer1.0-plugins-ugly \
+ gstreamer1.0-libav \
+ gstreamer1.0-nice \
+ python3-gi \
+ gir1.2-gstreamer-1.0
+```
+
+**macOS (with Homebrew):**
+```bash
+brew install gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly pygobject3
+```
+
+**Verify installation:**
+```bash
+gst-launch-1.0 --version
+# Should show GStreamer 1.20 or newer
+```
+
+### 2. Install Python Dependencies
+
+```bash
+pip install -r requirements-gstreamer.txt
+```
+
+This installs:
+- `PyGObject` - Python bindings for GStreamer
+- `aiohttp` - For WebRTC signaling (optional)
+- Other utilities
+
+---
+
+## Quick Start
+
+### Test 1: GStreamer Bridge (Passthrough)
+
+Test that GStreamer is working correctly with a simple passthrough:
+
+```bash
+python test_gstreamer.py --mode bridge
+```
+
+You should hear a 440Hz tone for 5 seconds. If you hear it, GStreamer is working!
+
+### Test 2: File-to-File Voice Conversion
+
+Convert a voice from one file to another using GStreamer:
+
+```bash
+python test_gstreamer.py --mode file \
+ --source examples/source.wav \
+ --reference examples/reference.wav \
+ --output output_converted.wav \
+ --diffusion-steps 10
+```
+
+### Test 3: Real-Time Voice Conversion (Local)
+
+Test real-time voice conversion with a test tone:
+
+```bash
+python test_gstreamer.py --mode realtime \
+ --reference examples/reference.wav \
+ --diffusion-steps 10
+```
+
+You should hear a 440Hz tone converted to the reference voice.
+
+### Test 4: Network Streaming (RTP)
+
+This test requires two terminals.
+
+**Terminal 1 (Send audio via RTP):**
+```bash
+gst-launch-1.0 filesrc location=examples/source.wav ! \
+ decodebin ! audioconvert ! audioresample ! \
+ audio/x-raw,rate=48000 ! opusenc ! rtpopuspay ! \
+ udpsink host=127.0.0.1 port=5004
+```
+
+**Terminal 2 (Run Seed-VC with GStreamer):**
+```bash
+python test_gstreamer.py --mode network \
+ --reference examples/reference.wav \
+ --input-port 5004 \
+ --output-port 5005
+```
+
+**Terminal 3 (Receive converted audio):**
+```bash
+gst-launch-1.0 udpsrc port=5005 caps='application/x-rtp' ! \
+ rtpjitterbuffer ! rtpopusdepay ! opusdec ! \
+ audioconvert ! autoaudiosink
+```
+
+---
+

+ host='127.0.0.1', # Output host
+ output_port=5005, # Output port
+ chunk_duration_ms=180.0 # 180ms chunks
+)
+```
+
+### Microphone to Speaker (Real-Time)
+
+```python
+from seed_vc_wrapper import SeedVCWrapper
+
+# Initialize wrapper
+vc = SeedVCWrapper()
+
+# Capture from microphone, play through speakers
+vc.convert_voice_gstreamer(

+---
+
+## Performance Tips
+
+### For Real-Time Conversion
+
+1. **Reduce diffusion steps**: Use 4-10 steps instead of 25-50
+ ```python
+ diffusion_steps=10 # Real-time (~150ms inference)
+ # vs
+ diffusion_steps=25 # High quality (~350ms inference)
+ ```
+
+2. **Use GPU**: Ensure CUDA is available
+ ```python
+ import torch
+ print(f"CUDA available: {torch.cuda.is_available()}")
+ ```
+
+3. **Adjust chunk size**: Smaller chunks = lower latency but more overhead
+ ```python
+ chunk_duration_ms=180.0 # Default, good balance
+ # vs
+ chunk_duration_ms=100.0 # Lower latency, more CPU
+ ```
+
+4. **Optimize network settings**: For RTP streaming
+ ```python
+ vc.convert_voice_gstreamer(
+ ...,
+ input_type='rtp',
+ port=5004,
+ latency=30, # Lower jitter buffer for lower latency
+ bitrate=64000 # Opus bitrate (higher = better quality)
+ )
+ ```
+
+### Expected Latency
+
+| Configuration | Algorithm | I/O | Network | Total |
+|---------------|-----------|-----|---------|-------|
+| Local (sounddevice) | 300ms | 130ms | - | **430ms** |
+| GStreamer (local) | 300ms | 50ms | - | **350ms** |
+| GStreamer (same region) | 300ms | 50ms | 60ms | **410ms** |
+| GStreamer (cross-continent) | 300ms | 50ms | 300ms | **650ms** |
+
+**Target**: <600ms for acceptable real-time experience
+
+---
+
+## Troubleshooting
+
+### "No module named 'gi'"
+
+**Solution:**
+```bash
+pip install PyGObject
+
+# If that fails, install system dependencies:
+sudo apt-get install libgirepository1.0-dev gcc libcairo2-dev pkg-config python3-dev gir1.2-gtk-3.0
+pip install PyGObject
+```
+
+### "Could not find element 'opusenc'"
+
+**Solution:**
+```bash
+sudo apt-get install gstreamer1.0-plugins-bad
+gst-inspect-1.0 opusenc # Verify it's installed
+```
+
+### High latency or audio dropouts
+
+**Solutions:**
+1. Reduce jitter buffer: `latency=20` (in ms)
+2. Increase GStreamer buffer: `max-buffers=20` (edit bridge code)
+3. Use faster GPU
+4. Reduce diffusion steps: `diffusion_steps=4`
+
+### "Pipeline errors: Could not link elements"
+
+**Solution:**
+Add `audioconvert ! audioresample !` between incompatible elements. This is already done in the bridge code, but if you modify pipelines manually, ensure format compatibility.
+
+### Audio quality issues
+
+**Solutions:**
+1. Increase Opus bitrate: `bitrate=128000` (default is 64000)
+2. Increase diffusion steps: `diffusion_steps=15` (default is 10)
+3. Use 44.1kHz model with F0: `f0_condition=True`
+
+---
+
+## Next Steps
+
+### Cloud Deployment
+
+For production cloud deployment:
+
+1. **Read the deployment guide**: [`GSTREAMER_INTEGRATION_ANALYSIS.md`](GSTREAMER_INTEGRATION_ANALYSIS.md#phase-3-production-deployment-week-5-6)
+
+2. **Build Docker container**: Use `Dockerfile.gstreamer` template in the analysis docs
+
+3. **Deploy to Kubernetes**: Use the provided k8s manifests
+
+4. **Set up WebRTC signaling**: For browser-based clients
+
+5. **Configure TURN server**: For NAT traversal (see `coturn` setup)
+
+### WebRTC Integration
+
+For browser-to-cloud voice conversion:
+
+1. **Implement WebRTC signaling server**: See `GSTREAMER_INTEGRATION_ANALYSIS.md` Phase 2
+
+2. **Create browser client**: HTML/JavaScript code provided in docs
+
+3. **Test end-to-end**: Browser → Cloud → Browser
+

+
+### Docker
+
+```dockerfile
+FROM node:18-alpine as build
+WORKDIR /app
+COPY package*.json ./
+RUN npm install
+COPY . .
+RUN npm run build
+
+FROM nginx:alpine
+COPY --from=build /app/build /usr/share/nginx/html
+EXPOSE 80
+CMD ["nginx", "-g", "daemon off;"]
+```
+
+Build and run:
+
+```bash
+docker build -t seedvc-client .
+docker run -p 80:80 seedvc-client
+```
+
+### Static Hosting
+
+Deploy the `build/` directory to:
+- Netlify
+- Vercel
+- AWS S3 + CloudFront
+- GitHub Pages
+- Any static host
+
+### HTTPS Requirement
+
+WebRTC requires HTTPS in production. Options:
+
+1. **Let's Encrypt** (free SSL)
+2. **CloudFlare** (free SSL + CDN)
+3. **AWS Certificate Manager**
+4. **Nginx reverse proxy** with SSL
+
+Example Nginx config:
+
+```nginx
+server {
+ listen 443 ssl http2;
+ server_name your-domain.com;
+
+ ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+ ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+ location / {
+ root /var/www/seedvc-client;
+ try_files $uri $uri/ /index.html;
+ }
+
+ # Proxy WebSocket connections to Janus
+ location /janus {
+ proxy_pass http://localhost:8188;
+ proxy_http_version 1.1;
+ proxy_set_header Upgrade $http_upgrade;
+ proxy_set_header Connection "upgrade";
+ }
+}
+```
+
+## Troubleshooting
+
+### "Janus library not loaded"
+
+- Check browser console for script loading errors
+- Ensure janus.min.js is loaded from CDN
+- Try refreshing the page
+
+### "Microphone access denied"
+
+- Grant microphone permission in browser
+- HTTPS is required (except localhost)
+- Check browser settings
+
+### "Connection failed"
+
+- Verify Janus Gateway is running: `curl http://localhost:8088/janus/info`
+- Check Janus server URL in settings
+- Verify network/firewall allows WebSocket connections
+
+### "No audio output"
+
+- Check browser console for WebRTC errors
+- Verify Seed-VC server is running
+- Check audio output device is working
+- Ensure not muted
+
+### High latency
+
+- Use wired internet connection
+- Close other bandwidth-heavy applications
+- Check server location (geographic distance)
+- Monitor performance metrics in app
+
+## Browser Support
+
+- ✅ Chrome/Edge 90+
+- ✅ Firefox 88+
+- ✅ Safari 14+
+- ✅ Opera 76+
+- ❌ IE (not supported)

+### Adding Features
+
+**Example: Add recording functionality**
+
+```javascript
+// In VoiceConversion.jsx
+const [recorder, setRecorder] = useState(null);
+
+const startRecording = () => {
+ const mediaRecorder = new MediaRecorder(localStream);
+ const chunks = [];
+
+ mediaRecorder.ondataavailable = (e) => chunks.push(e.data);
+ mediaRecorder.onstop = () => {
+ const blob = new Blob(chunks, { type: 'audio/webm' });
+ const url = URL.createObjectURL(blob);
+ // Download or upload recording
+ };
+
+ mediaRecorder.start();
+ setRecorder(mediaRecorder);
+};
+```
+
+### Testing
+
+```bash
+# Run tests
+npm test
+
+# Run with coverage
+npm test -- --coverage
+```
+
+## Performance
+
+Expected metrics on good connection:
+
+- **Latency:** 300-600ms
+- **Jitter:** <50ms
+- **Packet Loss:** <1%
+- **Bandwidth:** ~64kbps (Opus codec)
+
+## License
+
+Same as parent Seed-VC project
+
+## Support
+
+For issues:
+- Client-specific: Check browser console
+- Janus: https://groups.google.com/g/meetecho-janus
+- Seed-VC: See main project documentation

+# CloudFormation Templates for Seed-VC
+
+AWS CloudFormation templates for deploying Seed-VC infrastructure.
+
+## Overview
+
+This directory contains CloudFormation templates as an alternative to Terraform for deploying Seed-VC on AWS.
+
+**Template:** `seedvc-eks-cluster.yaml`
+
+Creates:
+- VPC with public/private subnets
+- EKS cluster with Kubernetes 1.28
+- GPU node group (g4dn.xlarge by default)
+- CPU node group (t3.medium by default)
+- ECR repository for Docker images
+- S3 bucket for model storage
+
+## Quick Start
+
+### Prerequisites
+
+- AWS CLI installed and configured
+- AWS account with EKS permissions
+
+### Deploy
+
+```bash
+# Create stack
+aws cloudformation create-stack \
+ --stack-name seedvc-production \
+ --template-body file://seedvc-eks-cluster.yaml \
+ --capabilities CAPABILITY_IAM \
+ --parameters \
+ ParameterKey=ClusterName,ParameterValue=seedvc-production \
+ ParameterKey=GPUNodeGroupDesiredSize,ParameterValue=3
+
+# Wait for completion (15-20 minutes)
+aws cloudformation wait stack-create-complete \
+ --stack-name seedvc-production
+
+# Get outputs
+aws cloudformation describe-stacks \
+ --stack-name seedvc-production \
+ --query 'Stacks[0].Outputs'
+```
+
+### Configure kubectl
+
+```bash
+aws eks update-kubeconfig --region us-west-2 --name seedvc-production
+```
+
+### Verify
+
+```bash
+kubectl get nodes
+```
+
+## Parameters
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| ClusterName | seedvc-production | EKS cluster name |
+| KubernetesVersion | 1.28 | Kubernetes version |
+| GPUInstanceType | g4dn.xlarge | GPU instance type |
+| GPUNodeGroupDesiredSize | 3 | Desired GPU nodes |
+| GPUNodeGroupMinSize | 3 | Min GPU nodes |
+| GPUNodeGroupMaxSize | 20 | Max GPU nodes |
+| CPUInstanceType | t3.medium | CPU instance type |
+| CPUNodeGroupDesiredSize | 2 | Desired CPU nodes |
+
+## Custom Parameters
+
+Create a parameters file:
+
+```json
+[
+ {
+ "ParameterKey": "ClusterName",
+ "ParameterValue": "seedvc-prod"
+ },
+ {
+ "ParameterKey": "GPUInstanceType",
+ "ParameterValue": "g5.xlarge"
+ },
+ {
+ "ParameterKey": "GPUNodeGroupDesiredSize",
+ "ParameterValue": "5"
+ }
+]
+```
+
+Deploy with parameters file:
+
+```bash
+aws cloudformation create-stack \
+ --stack-name seedvc-production \
+ --template-body file://seedvc-eks-cluster.yaml \
+ --parameters file://parameters.json \
+ --capabilities CAPABILITY_IAM
+```
+
+## Update Stack
+
+```bash
+aws cloudformation update-stack \
+ --stack-name seedvc-production \
+ --template-body file://seedvc-eks-cluster.yaml \
+ --parameters file://parameters.json \
+ --capabilities CAPABILITY_IAM
+```
+
+## Delete Stack
+
+**Warning:** This deletes ALL resources!
+
+```bash
+aws cloudformation delete-stack --stack-name seedvc-production
+```
+
+## Outputs
+
+After deployment, get outputs:
+
+```bash
+aws cloudformation describe-stacks \
+ --stack-name seedvc-production \
+ --query 'Stacks[0].Outputs' \
+ --output table
+```
+
+Example outputs:
+- ClusterEndpoint
+- ECRRepositoryURI
+- ModelsBucketName
+- ConfigureKubectl command
+
+## Cost Estimate
+
+Same as Terraform:
+- 3× g4dn.xlarge: $1.14/hour
+- 2× t3.medium: $0.08/hour
+- NAT Gateway: $0.045/hour
+- **Total: ~$1.29/hour (~$930/month)**
+
+## Comparison: CloudFormation vs Terraform
+
+| Feature | CloudFormation | Terraform |
+|---------|---------------|-----------|
+| **AWS Native** | ✅ Yes | ❌ No |
+| **Multi-Cloud** | ❌ No | ✅ Yes |
+| **State Management** | ✅ Automatic | ⚠️ Manual setup |
+| **Modularity** | ⚠️ Nested stacks | ✅ Excellent |
+| **Learning Curve** | Medium | Medium |
+| **Community** | Large (AWS) | Very large |
+
+**Recommendation:**
+- Use **CloudFormation** if you're AWS-only
+- Use **Terraform** if you need multi-cloud or prefer HCL syntax
+
+## Troubleshooting
+
+### Stack Creation Failed
+
+```bash
+# Get failure reason
+aws cloudformation describe-stack-events \
+ --stack-name seedvc-production \
+ --query 'StackEvents[?ResourceStatus==`CREATE_FAILED`]'
+```
+
+### EKS Cluster Not Accessible
+
+```bash
+# Update kubeconfig
+aws eks update-kubeconfig --region us-west-2 --name seedvc-production
+
+# Verify
+kubectl get svc
+```
+
+## Next Steps
+
+1. Configure kubectl (see output)
+2. Deploy NVIDIA device plugin
+3. Deploy Seed-VC application (see ../k8s/)
+4. Set up monitoring

+# Janus Gateway Configuration for Seed-VC
+
+This directory contains Janus Gateway configuration files for WebRTC voice conversion.
+
+## Configuration Files
+
+- `janus.jcfg` - Main Janus configuration
+- `janus.transport.websockets.jcfg` - WebSocket transport configuration
+- `janus.plugin.streaming.jcfg` - Streaming plugin configuration
+
+## Quick Start
+
+### Option 1: Using Docker Compose (Recommended)
+
+The docker-compose.yml already mounts this directory:
+
+```bash
+docker-compose up -d janus
+```
+
+### Option 2: Manual Janus Installation
+
+```bash
+# Install Janus (Ubuntu)
+sudo apt-get install libmicrohttpd-dev libjansson-dev \
+ libssl-dev libsrtp2-dev libsofia-sip-ua-dev libglib2.0-dev \
+ libopus-dev libogg-dev libcurl4-openssl-dev liblua5.3-dev \
+ libconfig-dev pkg-config gengetopt libtool automake
+
+# Clone and build Janus
+git clone https://github.com/meetecho/janus-gateway.git
+cd janus-gateway
+sh autogen.sh
+./configure --prefix=/opt/janus
+make
+sudo make install
+
+# Copy configuration
+sudo cp /path/to/seed-vc/janus-config/*.jcfg /opt/janus/etc/janus/
+
+# Start Janus
+/opt/janus/bin/janus
+```
+
+## Stream Configuration
+
+### Stream ID 1: Basic Voice Conversion
+
+**Sends audio TO Seed-VC:**
+- Janus receives WebRTC audio from browser
+- Forwards as RTP to `localhost:5004` (Seed-VC input)
+
+**Limitation:** Standard Janus streaming plugin is unidirectional. For bidirectional flow, use Stream ID 2 with bridge.
+
+### Stream ID 2: Bidirectional Voice Conversion (Recommended)
+
+Uses the bridge script (`janus_seedvc_bridge.py`) for full duplex:
+
+```
+Browser → Janus (WebRTC) → RTP:6000 → Bridge → RTP:5004 → Seed-VC
+Browser ← Janus (WebRTC) ← RTP:6001 ← Bridge ← RTP:5005 ← Seed-VC
+```
+
+**Start the bridge:**
+```bash
+python3 janus_seedvc_bridge.py \
+ --seedvc-input-port 5004 \
+ --seedvc-output-port 5005 \
+ --janus-input-port 6000 \
+ --janus-output-port 6001
+```
+
+## Testing
+
+### Test Janus is Running
+
+```bash
+# Check Janus info endpoint
+curl http://localhost:8088/janus/info
+
+# Expected response:
+# {"janus":"server_info","name":"Janus WebRTC Server",...}
+```
+
+### Test WebSocket Connection
+
+```bash
+# Using websocat (install with: cargo install websocat)
+websocat ws://localhost:8188/janus
+
+# Or use the browser client
+```
+
+### Test Audio Stream
+
+```bash
+# Send test audio to Janus stream
+gst-launch-1.0 audiotestsrc freq=440 ! audioconvert ! \
+ audioresample ! audio/x-raw,rate=48000,channels=2 ! \
+ opusenc bitrate=64000 ! rtpopuspay ! \
+ udpsink host=localhost port=5002
+```
+
+## SSL/TLS Configuration (Production)
+
+For production, enable HTTPS/WSS:
+
+1. **Get SSL certificate:**
+```bash
+# Using Let's Encrypt
+sudo certbot certonly --standalone -d your-domain.com
+```
+
+2. **Update configuration:**
+Edit `janus.jcfg`:
+```ini
+[certificates]
+cert_pem = /etc/letsencrypt/live/your-domain.com/fullchain.pem
+cert_key = /etc/letsencrypt/live/your-domain.com/privkey.pem
+```
+
+Edit `janus.transport.websockets.jcfg`:
+```ini
+[wss]
+enabled = yes
+port = 8989
+wss_certificate = /etc/letsencrypt/live/your-domain.com/fullchain.pem
+wss_key = /etc/letsencrypt/live/your-domain.com/privkey.pem
+```
+
+3. **Update browser client to use WSS:**
+```javascript
+server: 'wss://your-domain.com:8989/janus'
+```
+
+## STUN/TURN Configuration
+
+For NAT traversal, configure STUN/TURN servers:
+
+**Edit `janus.jcfg`:**
+```ini
+[general]
+stun_server = stun.l.google.com
+stun_port = 19302
+
+[nat]
+turn_server = turn:your-turn-server.com:3478
+turn_user = username
+turn_pwd = password
+```
+
+**Or use TURN REST API (recommended for dynamic credentials):**
+```ini
+[nat]
+turn_rest_api = https://your-domain.com/turn-credentials
+turn_rest_api_key = your-secret-key
+turn_rest_api_method = POST
+```
+
+## Troubleshooting
+
+### Janus won't start
+
+```bash
+# Check configuration syntax
+/opt/janus/bin/janus --check-config
+
+# View logs
+journalctl -u janus -f
+```
+
+### WebSocket connection fails
+
+```bash
+# Check Janus is listening
+netstat -tulpn | grep 8188
+
+# Check firewall
+sudo ufw allow 8188/tcp
+```
+
+### No audio in browser
+
+1. Check browser console for WebRTC errors
+2. Verify ICE connection state: `peerConnection.iceConnectionState`
+3. Check Janus logs: `/opt/janus/log/janus.log`
+4. Verify Seed-VC is receiving audio:
+ ```bash
+ # Listen on Seed-VC input port
+ nc -u -l 5004
+ ```
+
+### RTP not reaching Seed-VC
+
+```bash
+# Check if RTP packets are being sent
+tcpdump -i any -n udp port 5004
+
+# Test with manual RTP send
+gst-launch-1.0 audiotestsrc ! audioconvert ! \
+ audioresample ! audio/x-raw,rate=48000 ! \
+ opusenc ! rtpopuspay ! udpsink host=localhost port=5004
+```
+
+## Advanced: Custom Janus Plugin
+
+For tighter integration, you can create a custom Janus plugin that:
+1. Receives WebRTC audio
+2. Forwards to Seed-VC via RTP
+3. Receives processed audio
+4. Sends back via WebRTC
+
+This eliminates the need for the bridge script but requires C programming.
+
+See: https://janus.conf.meetecho.com/docs/plugin.html

+Complete AWS infrastructure as code for deploying Seed-VC with GPU support.
+
+## Architecture
+
+This Terraform configuration creates:
+
+- **EKS Cluster** with GPU nodes (NVIDIA T4/A10G)
+- **VPC** with public/private subnets across 3 AZs
+- **Application Load Balancer** for HTTP/WebSocket (Janus)
+- **Network Load Balancer** for RTP/UDP traffic
+- **ECR Repository** for Docker images
+- **S3 Bucket** for model storage
+- **CloudWatch** for logging
+- **Route53 + ACM** (optional) for custom domain + SSL
+
+### Cost Estimate
+
+**Development (3 GPU nodes, 2 CPU nodes):**
+- GPU: 3× g4dn.xlarge @ $0.526/hour = $1.14/hour
+- CPU: 2× t3.medium @ $0.042/hour = $0.08/hour
+- NAT Gateway: 1× $0.045/hour = $0.045/hour
+- ALB: $0.0225/hour
+- **Total: ~$1.29/hour (~$930/month)**
+
+**Production (10 GPU nodes, 5 CPU nodes):**
+- GPU: 10× g4dn.xlarge = $3.80/hour
+- CPU: 5× t3.medium = $0.21/hour
+- NAT Gateway: 3× $0.045/hour = $0.135/hour
+- ALB + NLB: $0.045/hour
+- **Total: ~$4.19/hour (~$3,017/month)**
+
+**Cost Optimization:**
+- Use spot instances: Save up to 70% on GPU costs
+- Use single NAT gateway: Save $0.09/hour ($65/month)
+- Use smaller instances during off-peak
+- Enable HPA to scale down when idle
+
+## Prerequisites
+
+1. **AWS Account** with appropriate permissions
+2. **AWS CLI** configured
+ ```bash
+ aws configure
+ ```
+3. **Terraform** 1.0+
+ ```bash
+ # Install Terraform
+ wget https://releases.hashicorp.com/terraform/1.6.0/terraform_1.6.0_linux_amd64.zip
+ unzip terraform_1.6.0_linux_amd64.zip
+ sudo mv terraform /usr/local/bin/
+ ```
+4. **kubectl** for Kubernetes management
+ ```bash
+ curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
+ sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
+ ```
+
+## Quick Start
+
+### 1. Configure Variables
+
+```bash
+cd terraform
+cp terraform.tfvars.example terraform.tfvars
+# Edit terraform.tfvars with your settings
+```
+
+### 2. Initialize Terraform
+
+```bash
+terraform init
+```
+
+### 3. Plan Infrastructure
+
+```bash
+terraform plan
+```
+
+Review the plan carefully. This will show you all resources to be created and estimated costs.
+
+### 4. Apply Infrastructure
+
+```bash
+terraform apply
+```
+
+Type `yes` when prompted. This will take 15-20 minutes to create the EKS cluster.
+
+### 5. Configure kubectl
+
+```bash
+aws eks update-kubeconfig --region us-west-2 --name seedvc-production
+```
+
+### 6. Verify Cluster
+
+```bash
+kubectl get nodes
+# You should see GPU and CPU nodes
+
+kubectl get nodes -L node.kubernetes.io/instance-type
+# Check instance types
+```
+
+### 7. Deploy Seed-VC
+
+```bash
+# Build and push Docker image
+cd ..
+docker build -t seedvc:latest .
+
+# Tag and push to ECR
+$(aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin YOUR_ECR_URL)
+docker tag seedvc:latest YOUR_ECR_URL/seedvc:latest
+docker push YOUR_ECR_URL/seedvc:latest
+
+# Deploy to Kubernetes
+kubectl apply -f k8s/
+```

+
+## Configuration
+
+### Key Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `aws_region` | `us-west-2` | AWS region |
+| `environment` | `production` | Environment name |
+| `gpu_instance_types` | `["g4dn.xlarge"]` | GPU instance types |
+| `gpu_nodes_desired` | `3` | Desired GPU nodes |
+| `gpu_nodes_max` | `20` | Maximum GPU nodes |
+| `domain_name` | `""` | Custom domain (optional) |
+| `spot_instances_enabled` | `false` | Use spot instances |
+
+### GPU Instance Types
+
+| Instance Type | GPU | vCPUs | RAM | Price/hour | Use Case |
+|---------------|-----|-------|-----|------------|----------|
+| `g4dn.xlarge` | 1× T4 | 4 | 16 GB | $0.526 | Development |
+| `g4dn.2xlarge` | 1× T4 | 8 | 32 GB | $0.752 | Production |
+| `g5.xlarge` | 1× A10G | 4 | 16 GB | $1.006 | Better performance |
+| `g5.2xlarge` | 1× A10G | 8 | 32 GB | $1.212 | Best performance |
+| `p3.2xlarge` | 1× V100 | 8 | 61 GB | $3.06 | High-end |
+
+**Recommendation:** `g4dn.xlarge` for most use cases (best price/performance)
+
+## Outputs
+
+After `terraform apply`, you'll see:
+
+```
+eks_cluster_endpoint = "https://XXX.eks.amazonaws.com"
+eks_cluster_name = "seedvc-production"
+alb_dns_name = "seedvc-alb-XXX.us-west-2.elb.amazonaws.com"
+nlb_dns_name = "seedvc-nlb-XXX.us-west-2.elb.amazonaws.com"
+ecr_repository_url = "123456789.dkr.ecr.us-west-2.amazonaws.com/seedvc"
+s3_models_bucket = "seedvc-production-models"
+configure_kubectl = "aws eks update-kubeconfig --region us-west-2 --name seedvc-production"
+```
+
+## Advanced Configuration
+
+### Enable Spot Instances (Save 70% on GPU costs)
+
+```hcl
+# terraform.tfvars
+spot_instances_enabled = true
+```
+
+**Pros:**
+- 60-70% cost savings
+- Same performance
+
+**Cons:**
+- Can be interrupted with 2-minute warning
+- Need to handle pod disruption
+
+### Custom Domain + SSL
+
+```hcl
+# terraform.tfvars
+domain_name = "voice.example.com"
+```
+
+This creates:
+- Route53 hosted zone
+- ACM certificate (requires DNS validation)
+- ALB listener rules for HTTPS
+
+**After apply:**
+1. Update your domain's nameservers to Route53 NS records
+2. Wait for ACM certificate validation (~5-30 minutes)
+3. Access your app at `https://voice.example.com`
+
+### Multi-Region Deployment
+
+```bash
+# Deploy to multiple regions
+terraform workspace new us-west-2
+terraform apply -var="aws_region=us-west-2"
+
+terraform workspace new eu-west-1
+terraform apply -var="aws_region=eu-west-1"
+```
+
+### Remote State (Recommended for Production)
+
+Create S3 bucket and DynamoDB table for state locking:
+
+```bash
+# Create state bucket
+aws s3api create-bucket \
+ --bucket your-terraform-state \
+ --region us-west-2 \
+ --create-bucket-configuration LocationConstraint=us-west-2
+
+aws s3api put-bucket-versioning \
+ --bucket your-terraform-state \
+ --versioning-configuration Status=Enabled
+
+# Create lock table
+aws dynamodb create-table \
+ --table-name terraform-locks \
+ --attribute-definitions AttributeName=LockID,AttributeType=S \
+ --key-schema AttributeName=LockID,KeyType=HASH \
+ --billing-mode PAY_PER_REQUEST \
+ --region us-west-2
+```
+
+Then uncomment backend configuration in `main.tf`.
+
+## Monitoring
+
+### CloudWatch Dashboards
+
+```bash
+# View logs
+aws logs tail /aws/eks/seedvc-production/seedvc --follow
+```
+
+### Cost Explorer
+
+```bash
+# View monthly costs
+aws ce get-cost-and-usage \
+ --time-period Start=2024-01-01,End=2024-01-31 \
+ --granularity MONTHLY \
+ --metrics BlendedCost \
+ --group-by Type=DIMENSION,Key=SERVICE
+```
+
+## Scaling
+
+### Manual Scaling
+
+```bash
+# Scale GPU nodes
+aws eks update-nodegroup-config \
+ --cluster-name seedvc-production \
+ --nodegroup-name gpu-nodes \
+ --scaling-config minSize=5,maxSize=30,desiredSize=10
+```
+
+### Auto-Scaling
+
+HPA is configured in `k8s/hpa.yaml`:
+- Scales based on CPU/GPU utilization
+- Min: 3 pods, Max: 20 pods
+- Target: 70% CPU, 80% GPU
+
+## Backup & Disaster Recovery
+
+### Backup EKS Configuration
+
+```bash
+# Backup all Kubernetes resources
+kubectl get all --all-namespaces -o yaml > k8s-backup.yaml
+
+# Backup to S3
+aws s3 cp k8s-backup.yaml s3://your-backup-bucket/
+```
+
+### Restore
+
+```bash
+# Restore from backup
+kubectl apply -f k8s-backup.yaml
+```
+
+## Troubleshooting
+
+### Nodes Not Ready
+
+```bash
+# Check node status
+kubectl describe node NODE_NAME
+
+# Check NVIDIA device plugin
+kubectl logs -n kube-system -l name=nvidia-device-plugin-ds
+```
+
+### Cannot Pull ECR Images
+
+```bash
+# Verify ECR permissions
+aws ecr get-login-password --region us-west-2 | docker login --username AWS --password-stdin YOUR_ECR_URL
+
+# Check IAM role permissions
+kubectl describe serviceaccount -n kube-system
+```
+
+### High Costs
+
+1. Check idle resources:
+ ```bash
+ kubectl top nodes
+ kubectl top pods
+ ```
+
+2. Enable HPA to scale down when idle
+
+3. Consider spot instances
+
+4. Use single NAT gateway for dev
+
+## Cleanup
+
+**Warning:** This will destroy ALL resources and delete data!
+
+```bash
+# Delete Kubernetes resources first
+kubectl delete -f k8s/
+
+# Destroy Terraform infrastructure
+terraform destroy
+```
+
+Type `yes` to confirm.
+
+## Best Practices
+
+1. **Use workspaces** for multiple environments
+2. **Enable state locking** with DynamoDB
+3. **Store state remotely** in S3
+4. **Tag all resources** for cost tracking
+5. **Use spot instances** for non-critical workloads
+6. **Enable auto-scaling** to optimize costs
+7. **Monitor costs** with AWS Cost Explorer
+8. **Set up alerts** for budget thresholds
+9. **Regularly update** Terraform and providers
+10. **Test in dev** before applying to production
+
+## Security
+
+- All traffic encrypted (TLS/DTLS-SRTP)
+- Private subnets for worker nodes
+- Security groups restrict access
+- IAM roles with least privilege
+- ECR image scanning enabled
+- Secrets stored in AWS Secrets Manager (add if needed)
+
+## Support

+For issues:
+- AWS EKS: https://docs.aws.amazon.com/eks/
+- Terraform: https://www.terraform.io/docs
+- Seed-VC: See main documentation

+Usage:
+ # Test 1: Bridge passthrough (you should hear a 440Hz tone)
+ python test_gstreamer.py --mode bridge
+
+ # Test 2: File-to-file voice conversion
+ python test_gstreamer.py --mode file --source examples/source.wav --reference examples/reference.wav --output output.wav
+
+ # Test 3: Real-time with test tone (you should hear a converted 440Hz tone)
+ python test_gstreamer.py --mode realtime --reference examples/reference.wav
+
+ # Test 4: Network streaming (run in two terminals)
+ # Terminal 1 (sender): gst-launch-1.0 filesrc location=source.wav ! decodebin ! audioconvert ! audioresample ! audio/x-raw,rate=48000 ! opusenc ! rtpopuspay ! udpsink host=127.0.0.1 port=5004
