StemGrab

StemGrab (stemgrab.com) is a free stem separation tool that splits any track into all 7 stems: vocals, drums, bass, guitar, piano, other, and instrumental. The core tool is free, always, with no sign-up: downloads come as full-quality MP3 or WAV with no watermark, and users can process as many tracks as they want, one after another, with no account and no daily limit. The free tool supports tracks up to 15 minutes long, and download links stay live for 45 minutes.

An optional 30-day pass adds practice tools on top of the free separation: slowing a stem down to 50% without changing its pitch, shifting the key up to ±7 semitones, and 6 play-along mixes that remove a chosen instrument from the full track. The pass also raises the track length limit to 60 minutes, allows dropping 10 tracks in at once instead of one after another, extends download link availability to 24 hours, and skips the queue with no ads. The pass is a one-off payment, not a subscription, and its 30 days start from the first track processed rather than from the moment of payment.

How StemGrab Works

Using the free tool is straightforward: upload a track, and StemGrab separates it into all 7 stems using the same underlying model and audio quality available with a pass, since nothing about audio processing is switched off on the free tier. Results download as full-quality MP3 or WAV with no watermark, and there's no account or daily cap on how many tracks can be processed, only a per-track length limit of 15 minutes and a 45-minute window before the download link expires. With a 30-day pass, users unlock additional practice-oriented tools: pitch-preserving tempo changes down to 50% speed, key shifting up to ±7 semitones, and 6 play-along mixes that remove a specific instrument from the full mix. The pass also extends the per-track limit to 60 minutes, lets users batch-process 10 tracks at once, keeps download links live for 24 hours, and removes the queue and ads.

Who Should Use StemGrab?

Musicians and hobbyists who just want a clean stem separation for a short track can rely entirely on the free tool, since it uses the same model and audio quality as the paid pass. Musicians practicing along to a song, who want to slow down or shift the key of a stem, or who need a play-along mix with a specific instrument removed, are the clearest fit for the 30-day pass. Anyone working with longer tracks, batch uploads, or who wants to skip the processing queue entirely should also consider the pass, especially since the same €5 payment unlocks several sister tools beyond just StemGrab.
