Frequently asked questions
Quick answers to the questions we hear most. Still stuck? Use the contact form.
Do I need an account?
No. Just upload a song and press Start. No sign-up required.
Will my songs be uploaded to a third party?
No. Your audio stays on this site’s own computer. Nothing is sent to another company for processing.
What model is used?
By default, Unmix uses a high-quality vocal remover for karaoke-style splits. You can also pick other models in the Model menu — including ones that separate drums, bass, and more. Choose what sounds best for your song.
Why is processing slow?
Stem separation is heavy work. Longer songs and higher-quality models take more time. A machine with a GPU is much faster; on CPU-only hosts, try a shorter clip first.
Which file formats are supported?
You can upload common formats like MP3, WAV, FLAC, and M4A. Output can be WAV, FLAC, or MP3 depending on what you pick in Output format.
