Stem separation, vocal removal and key/BPM analysis, in the browser
Separate a track into drums, bass, vocals and other instruments, pull the vocal off a mix, or read a track's tempo and musical key — all in the browser, nothing to install. Separation uses the HT-Demucs model with overlapping windows, so the stems have no seams at the segment joins. Key and BPM analysis is unlimited for members; separations are one a day.
3 Operations · 4-Stem Separation · Key & BPM
Subverse Splitter is a member-only web tool for analysing music and separating a track into stems. It offers three operations:
- Key and BPM estimates tempo, musical key, Camelot code, and key confidence. It does not use the daily separation allowance.
- Vocal removal returns the vocal and an instrumental version.
- Stem separation returns drums, bass, vocals, and other instruments.
Vocal removal and stem separation use the same HT-Demucs model and therefore cost the same daily separation run.
