Resepformer Wsj02mix

🚀 RE-SepFormer trained on WSJ0-2Mix

This repository offers all the essential tools for audio source separation. It utilizes a RE-SepFormer model, implemented with SpeechBrain and pre - trained on the WSJ0 - 2Mix dataset. For an enhanced experience, we recommend learning more about SpeechBrain. The model achieves a performance of 18.6 dB on the test set of the WSJ0 - 2Mix dataset.

🚀 Quick Start

This repository provides all the necessary tools to perform audio source separation with a RE-SepFormer model, implemented with SpeechBrain, and pretrained on WSJ0-2Mix dataset.

✨ Features

• Source Separation: Suitable for various source separation tasks, including speech separation and audio source separation.
• Pretrained Model: The model is pretrained on the WSJ0 - 2Mix dataset, with a test - set performance of 18.6 dB.
• SpeechBrain Integration: Implemented using the SpeechBrain framework.

📦 Installation

Install SpeechBrain

First, install SpeechBrain using the following command:

pip install speechbrain

💡 Usage Tip

We encourage you to read our tutorials and learn more about SpeechBrain.

💻 Usage Examples

Perform source separation on your own audio file

from speechbrain.inference.separation import SepformerSeparation as separator
import torchaudio

model = separator.from_hparams(source="speechbrain/resepformer-wsj02mix", savedir='pretrained_models/resepformer-wsj02mix')

# for custom file, change path
est_sources = model.separate_file(path='speechbrain/sepformer-wsj02mix/test_mixture.wav') 

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

⚠️ Important Note

The system expects input recordings sampled at 8kHz (single channel). If your signal has a different sample rate, resample it (e.g., using torchaudio or sox) before using the interface.

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.

🔧 Technical Details

Training

The model was trained with SpeechBrain (fc2eabb7). To train it from scratch, follow these steps:

1. Clone SpeechBrain:

git clone https://github.com/speechbrain/speechbrain/

2. Install it:

cd speechbrain
pip install -r requirements.txt
pip install -e .

3. Run Training:

cd  recipes/WSJ0Mix/separation
python train.py hparams/sepformer.yaml --data_folder=your_data_folder
