Alpha: what it does not do yet
- Quality is HTDemucs-class, not studio grade: expect some bleed between stems and artifacts on dense mixes.
- "Instruments" is everything that is not vocals, drums or bass (guitars, keys, synths together).
- First run downloads a 172 MB model from Hugging Face (cached afterwards). Desktop Chrome/Edge with WebGPU is fastest; CPU mode can take several minutes per song.
- One song at a time, up to 10 minutes and 100 MB. Phones and tablets are untested.
- Use it on your own tracks or for practice; you are responsible for having the rights to what you separate.
- Results are not saved: download the WAVs or send them to StemDeck before leaving the page.
