Free Stem Separator Online: Split Any Song Into Vocals, Drums, Bass, and Other

How to split a song into 4 individual stems — vocals, drums, bass, and other — for free in your browser, and when you need that instead of a simple vocal remover.

A vocal remover gives you two tracks: instrumental and vocal. A stem separator goes further and splits a song into four: vocals, drums, bass, and other (everything else — synths, guitars, pads). That's the tool to reach for when "instrumental" isn't granular enough for what you're trying to do.

How to split a song into 4 stems for free

  1. 1

    Open a free stem separator

    BeatShort's Stems tool runs in the browser, no account or software install.

  2. 2

    Upload the track

    MP3, WAV, or most common audio formats.

  3. 3

    Run the split

    The track is separated into vocals, drums, bass, and other.

  4. 4

    Download the stems you need

    Keep all four, or just the one or two you actually want.

When you need 4 stems instead of just vocal/instrumental

  • Remixing — isolating drums or bass to rebuild a track around a different arrangement.
  • Practicing an instrument — muting everything except bass or drums to play along.
  • Sampling — pulling just one element (a bassline, a drum pattern) out of a full mix.
  • A cleaner vocal isolation — separating drums and bass out of the "instrumental" bucket can reduce bleed compared to a 2-stem split.

If all you actually need is an instrumental to sing over, or an isolated vocal, the simpler 2-stem vocal remover is the faster tool — 4 stems is for when you specifically need drums and bass separated too, not just lumped into one "everything else" track.

Want to remix, not just isolate?

Stems gives you the separated tracks to work with elsewhere. If you want per-stem EQ, filter, and reverb control built into the same tool, see Audio Remix — a DJ-style mixing surface built on the same separation.

FAQ

Is 4-stem separation as clean as a simple vocal/instrumental split?
Both are built on the same underlying separation technology — 4 stems just reports the split at finer granularity. Quality depends mainly on the source mix, same as any separation.
Do I need all 4 stems, or can I download just one?
You can keep just the stem(s) you actually need — there's no requirement to use all four.
