Free AI-based music demixing web app

In music demixing or music source separation, AI models are used to
separate the different instruments from a music recording into stems.
This web application allows you to demix your music files, free and
with no usage limits since it runs on your computer! 

Load a song to decompose it into bass, drums, vocals, other, and
karaoke using a near-state-of-the-art AI model, Open-Unmix with the
UMX-L pretrained weights. This site is created and maintained by
Sevag H.

Runs locally in your browser!

Unlike similar products, it's free to use and doesn't store your
data. All processing is done in your browser, and your files are
never uploaded anywhere. It runs well on computers and very slowly on
smartphones; user beware.

Demo

For the demo, I used a free song by Jaxius Music, which you can also
download if you don't have any music files handy.

Here's a demo of 20 seconds of demixed outputs; press the play button
and toggle sources to add or remove them from the mix:

Latest news

  * Improved demixing quality by 1+ dB SDR with Wiener filtering
  * Support demixing larger tracks with low-memory segmented
    inference and streaming LSTM
  * Added batch demixing and a checkbox to show developer output logs

Disclaimers!

  * You can only use the outputs for non-commercial applications as
    per the UMX-L weights license
  * The task is CPU and memory intensive (up to 4 GB), please be
    patient! Very very large tracks may still crash!
  * Please open a GitHub Issue for any bugs or feature requests.
  * Input files can be almost any audio format, but the outputs are
    always stereo wav files @ 44100 Hz
