MSS_WaveUNet

Music source separation using WaveUNet(https://arxiv.org/pdf/1806.03185.pdf)

Separate 4 audio stems(vocal, drum, bass, others) from music.

Setup

  1. clone this repository
  2. install requirements
python -m pip install -r requirements.txt
  1. install ffmpeg

for linux:

sudo apt install ffmpeg

for windows:
go to ffmpeg installation webpage(https://ffmpeg.org/download.html#build-windows) and download ffmpeg executable file and add downloaded directory's path(path\ffmpeg\bin) to your environment variable Path.

Train

You can train WaveUNet model with MUSDB18 dataset.

  1. download musdb18 dataset(https://sigsep.github.io/datasets/musdb.html#musdb18-compressed-stems)
  2. unzip musdb18.zip or musdb18hq.zip
  3. process the mp4 musdb dataset to numpy arrays. in data directory, you can use process.py to separate mp4 audio data into mp3 audio stems, and convert them into the same length array segments.
python process.py path/to/musdb18/dataset path/to/save
  1. train the model using train.py. if you have processed the musdb18 dataset with process.py, the directory of the train dataset will be path/to/save/train/data_split, and the test dataset will be path/to/save/test/data_split.
python train.py path/train/data_split path/test/data_split
  1. the best model(by validation loss, using early stopping) will be saved as model.pt.

Or, you can use your own dataset to train the WaveUNet model, but you may need to use your own data processing method or script.

Predict

You can separate the music into 4 stems using predict.py: vocal, drum, bass, and others. Result of the prediction will be saved in output/song_out_n.wav. n will be the stem numbers, from 0 to 3, each means the drum, bass, others, and vocal.

python predict.py --path_model model.pt --path_song path/to/song.mp3

Notes

This is just the trial of implementation of WaveUNet. The models are not may as good as the result of the original paper, or the other implementations.
