May I ask why the audio length after noise reduction is inconsistent

[Marootc]

The duration of the denoised audio is inconsistent. May I ask what the problem is? I am currently working on saving the denoised audio locally, but there is a discrepancy between the denoised audio and the original audio
`def denoise_audio(audio_path, output_path):
dwav, sr = torchaudio.load(audio_path)
dwav = dwav.mean(dim=0)
wav_denoised, _ = denoise(dwav, sr, device)
if wav_denoised.ndim == 1:
wav_denoised = wav_denoised.unsqueeze(0)

wav_denoised_tensor = torch.from_numpy(wav_denoised.cpu().numpy())


sf.write(output_path, wav_denoised_tensor.T, 24000)`

denoise returns a sample rate
sf.write(output_path, wav_denoised_tensor.T, [use the return sample rate here] )`
