Audio Troubleshooting Guide
When output audio contains crackling or static, follow these steps:
- Sampling Rate VerificationConfirm that the sample rate parameter for audiofile.write is exactly 22050Hz, matching the model settings.
- Data Normalization CheckBefore saving the audio, execute `audio = mx.clip(audio, -0.99, 0.99)` to prevent amplitude overflow.
- Temperature Parameter AdjustmentExcessively high temp values may cause instability. We recommend gradually reducing the value from 0.7 to 0.3 to test the effect.
- Elimination of Environmental InterferenceClose other audio applications before running to prevent system-level sampling conflicts.
Advanced Processing Solution: Apply post-processing to the generated audio using the librosa library, incorporating limiter and noise gate filtering. Sample code can be referenced in librosa.effects.preemphasis.
