mp3, wav, flac and other common formats, up to 30 minutes per track.
A multi-stem Demucs model separates the bass from drums, vocals and the rest of the arrangement.
Get the bass as its own audio file — and every other stem from the same run if you need them.
Hearing the bass alone makes transcribing parts dramatically easier than picking it out of a full mix.
Use the other stems as a bassless backing track and take the bass player's seat yourself.
The stem keeps the original instrument's tone and playing nuances — it's the actual recording, isolated.
Transcribing bass from a full mix is hard: the low end blurs together with the kick drum, and it's easy to lose the exact notes and rhythm. Once the bass is on its own, the pitch and timing jump out — you can loop a phrase, slow it down in your DAW and play along until it's in your fingers. For students and gigging players this turns an evening of guessing into a few minutes of clear listening.
The isolated stem keeps the instrument's real tone and articulation — slides, ghost notes, the pick or finger attack — so you're learning the actual part, not an approximation.
Producers sample isolated bass lines to reuse a groove or to study how a track's low end was arranged against the drums. A/B the bass stem against your own mix to check tuning and feel, or drop the other stems together for a bass-free backing track and record your own line over the top.
Clean electric and acoustic bass separates reliably. Very wide or heavily layered synth bass can split between the bass and "other" stems depending on how it was designed, so give dense electronic tracks a quick preview before you commit.
Upload the song to TrackStemLab and pick a multi-stem model. The AI returns the bass as a separate audio file along with the other stems.
Yes — combine the other stems (vocals, drums, instruments) and you have a no-bass version of the song to practice over.
Yes — every account gets free processing minutes each day, with paid minutes available for heavier use.
Usually yes. Very wide or heavily layered synth basses may be split between the bass and 'other' stems, depending on the sound.
Transcribe and learn parts, sample lines for your own production, or analyze the arrangement — the stem is a regular audio file that works in any DAW.
