Spleeter
What it is
Spleeter is Deezer’s free, open-source library for separating vocals and instruments from audio files or rebuilding multitracks from a mixed recording. Pre-trained models produce two stems—vocals and accompaniment—or four and five stems that add drums, bass, piano, and other sound. Developers can train models with datasets of isolated sources. Written in Python and using TensorFlow, Spleeter runs from the command line or as a Python library, and it can be installed with pip or used through Docker. Deezer says four-stem separation can run 100 times faster than real time on a GPU. Suggested uses include instrumental creation, audio restoration and remastering, DJ mixes, and extracting voice tracks for subtitling. The project lists Spleeter 4 Max for Ableton Live and professional audio products using its models. Spleeter Free costs nothing; Spleeter Pro is an enterprise API with contact-required pricing.
For and against
For
- Open-source library with free plan
- Supports two-, four-, and five-stem models
- Available through CLI and Python library
- Can install with pip or Docker
- Offers API access through Pro
Against
- No desktop app
- Apple M1 TensorFlow issues are documented
- Copyright processing requires rights-owner authorization
- Pro pricing requires contacting Deezer
The verdict
Spleeter offers flexible source separation for developers, with multiple stem models and deployment methods. Users should account for its desktop-app absence, platform caveats, and rights obligations.
Who it suits
Spleeter suits developers and companies building audio-separation workflows or integrations. It is also relevant for instrumental creation, restoration, DJ mixing, and voice extraction.
