Split any track into clean, individual stems using real open-source source-separation technology, not a low-quality EQ trick. Pick exactly which stems you need: an isolated vocal for a remix, a full instrumental for a cover or karaoke track, or the complete multitrack breakdown (drums, bass, other instruments, and vocals) for sampling and production. Just need the vocals out or an instrumental? Try the dedicated Vocal Remover instead. Only pay for the stems you actually pick.
This tool uses Demucs, a state-of-the-art open-source AI source-separation model, the same category of technology used by professional remix and karaoke tools. Isolation quality is very good on most modern, well-produced mixes, though extremely dense arrangements or heavily processed vocals can still leave faint artifacts, which is inherent to any current AI separation technology, not a limitation specific to this tool.
Vocal Remover is a focused, cheaper entry point into this same engine limited to just vocals and instrumental. The Stem Isolator adds drums, bass, and other instruments as individually selectable stems, for full multitrack remixing and sampling work Vocal Remover can't do.
Each stem you keep is a separate deliverable file, so pricing scales with how many you take beyond the first two: isolating just vocals and instrumental costs the same flat rate, while taking the full multitrack breakdown costs more. You only pay for what you actually need.
MP3, WAV, FLAC, M4A, and OGG are all supported, up to 80MB per file. Separated stems are delivered as downloadable MP3 files and are also available to stream directly in your browser.
Not as separate files. The model splits a song into four parts: vocals, drums, bass and other instruments. Piano, guitar, synths, strings and everything else that is not vocals, drums or bass end up together in the Other Instruments stem. You can also take the Instrumental, which is the whole song without the vocals.
