RNNoise

✓ from pyrnnoise import RNNoise

✗ from pyrnnoise import RNNoise

Load a noisy audio file, filter it with RNNoise, and save the denoised result.

from pyrnnoise import RNNoise import soundfile as sf denoiser = RNNoise() data, samplerate = sf.read('noisy_audio.wav') output = denoiser.filter(data) sf.write('denoised_audio.wav', output, samplerate)

Debug

Known issues

breakingThe RNNoise class expects audio data as a numpy array of shape (N,) with dtype float32. Providing int16 or multichannel data will cause silent errors or poor results.

fix

Convert to float32 and ensure mono: audio = audio.astype(np.float32) / 32768.0 for int16 input.

affects: all

gotchaThe filter() method expects the entire audio at once; it does not support streaming or chunked processing out of the box. Attempting to call filter() on small chunks may produce artifacts at boundaries.

fix

Process the whole audio array in one call, or implement overlap-add for streaming.

affects: all

deprecatedThe 'sample_rate' parameter in RNNoise constructor is deprecated and ignored; the model always operates at 48 kHz. Passing it may raise a warning in future versions.

fix

Remove the sample_rate argument; resample your audio to 48 kHz before passing to denoiser.

affects: 0.4.0+
