Lossless files separate a little cleaner than MP3.
What to expect, honestly
We run an open-source separation model on our own servers. On clean, sparse mixes the stems are very usable; on dense, loud mixes you will hear some bleed, for example hi-hats in the vocal stem or a little vocal in "other". That is the model's limit, not something a setting fixes. Great for remixes, mashups, practice tracks and sampling; not a replacement for the original multitrack.
Free. Your stems are ready in about a minute per three minutes of song.

How it works
01
Upload a song
Any mixed track up to 10 minutes. It is decoded to 44.1 kHz stereo and handed to the separation engine.
02
Neural stem separation
A network trained on multitrack recordings estimates which part of the sound is vocals, drums, bass and everything else, a minute at a time.
03
Mix, solo, download
Audition each stem in the mixer, then download the WAV files one by one or as a zip.
Questions
Is it really free?
Yes. Create a free account, upload a song, download the four stems. No credits, no watermark, no subscription. The limit is 5 songs a day per account so the servers stay fast for everyone.
How clean are the stems?
It depends on the mix. Sparse arrangements separate very cleanly; dense, loud mixes leave bleed, most often hi-hats in the vocals and a little vocal in "other". We use an open-source model whose licence lets us offer this for free; studio-grade separation needs models we cannot license for a free service. The stems are a strong starting point for remixes, mashups, DJ edits, practice tracks and sampling, not the original multitrack.
Can I get guitar or piano on their own?
Not yet. The four-stem split is vocals, drums, bass and other; guitars, keys and synths are in "other".
What files do I get?
Four 16-bit 44.1 kHz WAV files, one per stem, available for 7 days. The zip is built in your browser from the four files.
Can I use the stems commercially?
That depends on the rights to the song you uploaded, not on us. If you own the recording or have permission from its rights holders, what you make with the stems is yours.
Which open-source engine powers this?
Open-Unmix with its MIT-licensed umxhq weights. Our open-source page lists every engine, licence and version.
