Stem Splitter: Split a Song into 6 Stems for Practice

Split a song into six stems

StemSplitterLab is a free stem splitter for practice. Open a song you already have and it comes apart into six stems: vocals, drums, bass, guitar, piano, and other. Other is whatever remains, usually strings, synths, organ, and pads. Each stem gets its own fader, mute, and solo, so you can hear one part on its own or the band without it.

It runs in your browser, and your song isn't uploaded. There's no account. The first visit downloads the separation file once, about 136 MB, and later songs reuse it.

Pick the part you play

Every page uses the same split. They differ in which stem starts muted. This is also where you separate instruments from song files you already have.

By task: chords, loop, karaoke, backing track, remove piano.

• Singers: the vocal remover mutes the lead vocal and leaves a backing track to sing over. Six ways to remove vocals compares that with the other methods.
• Drummers: the drum remover makes a drumless track, with a count-in ready. Five free ways to remove drums compares that with the other methods.
• Bass players: the bass remover takes the bass line out and leaves the kick and the band.
• Guitarists: the guitar remover mutes the guitar stem. Piano stays up. Other starts down as well, so pads do not sit on top of you until you raise that fader.
• Tempo or key first? The BPM and key finder reads both without splitting anything.

Practice tools on the same player

After the split, the player works like a practice room. Set an A–B loop around the bar you keep missing. Slow it down without changing the pitch, or move the pitch in semitones without changing the speed. Turn on the metronome or a count-in once the drums are gone, and let the speed trainer nudge the tempo up after a few clean passes. Drop markers on the verse and the bridge so you can jump between them.

When the mix sounds right, export it as WAV or MP3, or save a single stem as WAV.

What to expect from a split

No split is perfect, and it helps to know where this one slips. Vocals, drums, and bass usually come out cleanest. Guitar and piano are harder, especially a distorted guitar or a piano buried under pads. Reverb printed on a vocal can leave a faint tail after the vocal is muted. A dry studio mix splits more cleanly than a live room recording. For practice that's usually fine: you need the part out of the way, not a studio master.

On a slower computer, judge the six-second preview before running a whole song. Files open as mp3, wav, flac, m4a, or mp4, up to 20 minutes long.
