Drum Separator — Split Drums into Parts Online

Either. A drum track (a stem, a loop, a kit recording) is split into parts straight away. A whole song is recognized by the tool, which offers to take the drums out of it first with a separate neural network — it runs in your browser on the graphics card (WebGPU is required) and downloads its model once. Without that step the three drum models are useless on a song: they learned from drums alone and take the music for hits.

No separate model splits them — that part is what remains after subtracting kick, snare and toms from the source. This way the four parts add up to exactly the original track and nothing is lost at the seams; studio practice also keeps cymbals and overheads together.

The kick comes out almost without bleed; snare and toms with slight residue on dense passages. The models were trained on live drummers in eight kit sounds, so they recognize parts by their role in the groove rather than by one specific timbre.

Download the WAVs for your own software or press “Open in mixer” — the four tracks land on the audio mixer’s faders where you can set balance and EQ and export the mix as one file.

Whether your machine can run the model on the graphics card. With WebGPU available, a four-minute track separates in a few seconds; without it, the same track takes a minute or two on the processor. Nothing else changes the picture much — length scales linearly, and stereo costs no more than mono. The first run also pays for the models themselves, three downloads of about twenty megabytes, after which they stay in the browser and every later track starts immediately. If a laptop is unexpectedly slow, check that the browser is not running in a power-saving mode: that alone turns hardware acceleration off.

Drop the parts you do not want with the M button on the console (or keep the ones you do with S) and press “Download mix” — it saves exactly what you hear. The four parts add up to the original track, so the subtraction is exact, with no seams.

Yes. Right after the split the tool finds the kick, snare and tom hits, shows their count and the tempo, and the “Download MIDI” button hands back a Standard MIDI File in the GM drum map on channel 10 — any DAW opens it.

Upload the song and choose “Take the drums out and split them”. When the run ends the console shows five tracks: the music without drums and the four drum parts. “Without drums” mutes all the drum parts at once, and “Download mix” saves what you hear — the song without drums. The tracks add up to the original file, so nothing but the drums leaves the song.
