This repository dockerizes adefossez Demucs to split music tracks into different tracks (bass, drums, voice, others).

git clone https://github.com/stevemisel/docker-adefossez-demucs.git demucs

1. Copy the track you want to split into the input folder (e.g., input/mysong.mp3).
2. Execute demucs via the run job in the Makefile, specifying the track argument with only the name of the file:

make run track=mysong.mp3

This process will take some time the first time it is run, as the execution will:

• Download the Docker image that is setup to run the adefossez demucs script.
• Download the pretrained models.
• Execute demucs to split the track.

Subsequent runs will not need to download the Docker image or download the models, unless the model specified has not yet been used.

The following options are available when splitting music tracks with the run job:

Example commands:

# Use the "fine tuned" demucs model
make run track=mysong.mp3 model=htdemucs_ft

# Enable Nvidia CUDA support and output separated audio in mp3 format
make run track=mysong.mp3 gpu=true mp3output=true

To experiment with other demucs options on the command line, you can also run the Docker image interactively via the run-interactive job. Note that only the gpu option is applicable for this job.

Example:

make run-interactive gpu=true

The Docker image can be built locally via the build job:

make build
