Some Whisper models (especially large-v3 and large-v3-turbo) experience phrase repetition loops when context window optimization is enabled. This change disables the optimization by default for maximum compatibility while making it safer when explicitly enabled. Changes: - Default context_window_optimization to false - Add no_context=true when optimization is enabled (prevents repetition) - Use more conservative formula with minimum threshold (384 frames) - Align audio_ctx to multiple of 8 for GPU backend compatibility - Update documentation and troubleshooting guide Closes #124 Co-authored-by: Christopher Albert <albert@alumni.tugraz.at>
