Vocals, drums, bass, piano, guitar and everything else, each on its own track: mix them live in the studio, mute your own instrument to play along, or download every part as a 320 kbps MP3.
Pro allows 15 min on Standard · 6 min on High Quality
A stem is one group of instruments from a song, exported as its own audio file. Producers receive stems from the studio; everyone else has only the finished mix. The stem splitter recovers them with neural networks trained on multitrack recordings, which learn what a voice, a drum kit, a bass, a piano and a guitar sound like and pull each one out of the mix.
The stems open in a studio in your browser, one track each, ready to mix. Turn the drums up, mute the bass and play it yourself, solo the guitar to learn the part, or download any stem on its own.

Two stems split a song into the voice and everything else: the cleanest choice for karaoke and acapellas. Four stems add the drums and the bass, with the rest of the music in one "other" stem. Six stems also give the piano and the guitar their own tracks, which is what you need to learn or replace one of them.
The "other" stem holds everything the model has no separate stem for: strings, synths, horns, organ and effects. On a song without piano or guitar, those stems stay almost silent.
Every stem arrives as a track in the studio: horizontal lanes with waveforms you can click to jump, or classic vertical channel strips. Each track has volume and pan knobs, mute and solo, stereo meters and an effect rack (low cut, three-band EQ, compressor, transpose, echo, reverb and more), so you can hear a new balance before you download anything. A saved project opens again exactly as you left it.
Vocals, drums and bass separate very cleanly on studio recordings. Piano and guitar are harder, because they share their range with other instruments; on dense arrangements a little of one can be heard in the other.
Mazmazika is not affiliated with Ultimate Vocal Remover, but it runs the same openly available models that UVR users download: MDX-Net models (Voc FT, Inst HQ 3 and Kara 2) for the voice and the instrumental, and Demucs v4 for 4 and 6 stems. They run on our GPUs, so you get that quality in the browser, on a phone too, with nothing to install and no graphics card of your own.
Yes. Each track in the studio has its own download, and "Download all" gives a ZIP with every track. Downloads render exactly what you hear, with or without the effects.
MP3 at 320 kbps on the Ultra and High Quality engines, and 128 kbps on Standard.
Each engine has a per-run track length that depends on your plan; the exact minutes are listed under Free vs Pro above and on the tool itself.
The separation is yours, but the recording keeps its copyright. Practice, study and private remixes are fine; releasing music built on someone else's stems needs a licence from the rights holder.
