Spleeter

Isolate any vocal or instrumental track in an audio file

What Spleeter offers

Spleeter is a solution for recreating multitracks from a flat audio file, whether for a song, podcast, movie, game, etc. Our model extracts voice and instruments from music or any audio source and separates them from the rest of the file.

Fast

Get the track you need in just a few seconds.

Scalable

Work on large catalogs you own automatically.

Efficient

Use the existing file, no need to re-record.

The tool also enables us to improve our recommendation engines and will open opportunities to build playlists around specific attributes, like a particular piano quality, for example.

For developers

Spleeter Pro - coming soon

We are now developing Spleeter Pro, a faster, more efficient and accurate version, that will be available as an API.

You can already try our open source version below and reach out to learn more about Spleeter Pro.

Spleeter Free - open source

Our source separation library uses Tensorflow and comes with pre-trained models written in Python. You can use it straight from command line as well as directly via your own development pipeline as a Python library. It can be installed with Pip or used with Docker.

The library 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.
