What is a stem?
A stem is one instrument pulled out of a recorded song: the drums, the bass, the vocals and so on. With stems you can switch parts off and on.
Which model should I pick?
The default is a good choice for most songs. Pick another when you want a faster result or guitar and piano as their own parts.
- htdemucs_ft (default), 337 MB to download. The best quality of the three and the default. Four parts (drums, bass, vocals and the rest). About four times slower than htdemucs.
- htdemucs, 84 MB to download. The base model. Four parts, fast, slightly lower quality.
- htdemucs_6s, 55 MB to download. Adds guitar and piano as their own parts. Those two are experimental and can show bleed or artefacts.
Why is it slow the first time?
Jamn downloads a model the first time you use it, and the higher-quality models take longer to run. Later songs skip the download.
Where are my songs saved?
In the Mac app, on your Mac, in a songs folder you can change in Jamn > Settings. Mixtapes list the songs you have kept.
Which songs can I use?
Audio files you upload. You must hold the rights to use them.
