always error: LiveKitKrispNoiseFilter Process failed, channel: 0

[SleepAt11]

I've strictly followed the guideline of documentations https://docs.livekit.io/recipes/enhanced-noise-cancellation/ , which says it only needs 3 lines of code:

let krispProcessor = LiveKitKrispNoiseFilter()

AudioManager.shared.capturePostProcessingDelegate = krispProcessor

yourRoom.add(delegate: krispProcessor)

I got same issue: LiveKitKrispNoiseFilter Process failed, channel: 0

Any update on this? I'm having the same issue. Also seeing a lot of these errors in the logs:

KRISP-CIT: Krisp failed to set wt file
LiveKitKrispNoiseFilter GlobalInit Failed

And then after connecting to the room and beginning a conversation with the agent, I see this:

LiveKitKrispNoiseFilter disabled - This feature is supported only on LiveKit Cloud.

I have followed the integration guide exactly

I changed the initialization of the krisp processor to be at the module level and it solved the problem.

you can look at example-krisp-app as an example.

import LiveKit
import LiveKitKrispNoiseFilter
import SwiftUI

let filter = LiveKitKrispNoiseFilter() // initialize here and not as a property of the struct.
let room = Room()

struct ContentView: View {
    var body: some View {
...

cheers.

Followed your advice and the init errors have disappeared which is great. I now see this:

KRISP-CIT: KrispProcessor Init sample_rate_hz: 16000 num_channels: 1

However, I'm still seeing this error after starting a conversation:

LiveKitKrispNoiseFilter disabled - This feature is supported only on LiveKit Cloud.

Not sure whether it's actually working or not

Are you running the server locally or on the livekit cloud?
