About

Spleeter is Deezer source separation library with pretrained models written in Python and uses Tensorflow. It makes it easy to train source separation model (assuming you have a dataset of isolated sources), and provides already trained state of the art model for performing various flavour of separation :

  • Vocals (singing voice) / accompaniment separation (2 stems)
  • Vocals / drums / bass / other separation (4 stems)
  • Vocals / drums / bass / piano / other separation (5 stems)

2 stems and 4 stems models have high performances on the musdb dataset. Spleeter is also very fast as it can perform separation of audio files to 4 stems 100x faster than real-time when run on a GPU.

We designed Spleeter so you can use it straight from command line as well as directly in your own development pipeline as a Python library. It can be installed with Conda, with pip or be used with Docker.

Projects and Softwares using Spleeter

Since it's been released, there are multiple forks exposing Spleeter through either a Guided User Interface (GUI) or a standalone free or paying website. Please note that we do not host, maintain or directly support any of these initiatives.

That being said, many cool projects have been built on top of ours. Notably the porting to the Ableton Live ecosystem through the Spleeter 4 Max project.

Spleeter pre-trained models have also been used by professionnal audio softwares. Here's a non-exhaustive list:

Quick start

Want to try it out but don't want to install anything ? We have set up a Google Colab.

Ready to dig into it ? In a few lines you can install Spleeter using Conda and separate the vocal and accompaniment parts from an example audio file:

# install using conda
conda install -c conda-forge spleeter
# download an example audio file (if you don't have wget, use another tool for downloading)
wget https://github.com/deezer/spleeter/raw/master/audio_example.mp3
# separate the example audio into two components
spleeter separate -i audio_example.mp3 -p spleeter:2stems -o output

You should get two separated audio files (

vocals.wav
and
accompaniment.wav
) in the
output/audio_example
folder.

For a detailed documentation, please check the repository wiki

Development and Testing

The following set of commands will clone this repository, create a virtual environment provisioned with the dependencies and run the tests (will take a few minutes):

git clone https://github.com/Deezer/spleeter && cd spleeter
python -m venv spleeterenv && source spleeterenv/bin/activate
pip install . && pip install pytest pytest-xdist
make test

Troubleshooting

Spleeter is a complex piece of software and although we continously try to improve and test it you may encounter unexpected issues running it. If that's the case please check the FAQ page first as well as the list of currently open issues

Windows users

It appears that sometimes the shortcut command

spleeter
does not work properly on windows. This is a known issue that we will hopefully fix soon. In the meantime replace
spleeter separate
by
python -m spleeter separate
in command line and it should work.
