SepFormer trained on WHAM!

This repository provides all the necessary tools to perform audio source separation with a SepFormer model, implemented with SpeechBrain, and pretrained on WHAM! dataset, which is basically a version of WSJ0-Mix dataset with environmental noise. For a better experience we encourage you to learn more about SpeechBrain. The given model performance is 16.3 dB SI-SNRi on the test set of WHAM! dataset.

Install SpeechBrain

First of all, please install SpeechBrain with the following command:

pip install speechbrain

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Perform source separation on your own audio file


from speechbrain.pretrained import separator
import torchaudio

model = separator.from_hparams(source="speechbrain/sepformer-wham")

mix, fs = torchaudio.load("yourspeechbrainpath/samples/audio_samples/test_mixture.wav")

est_sources = model.separate(mix)
est_sources = est_sources / est_sources.max(dim=1, keepdim=True)[0]

torchaudio.save("source1hat.wav", est_sources[:, :, 0].detach().cpu(), 8000)
torchaudio.save("source2hat.wav", est_sources[:, :, 1].detach().cpu(), 8000)
