StemRoller
Free desktop app for one-click stem separation
About
StemRoller is a free, open-source desktop app that splits any song into vocals, drums, bass and other stems using Meta's Demucs algorithm, with a built-in search so you just type a song title and hit split. It also auto-generates an instrumental by merging the non-vocal stems. Splitting takes several minutes per track, Linux is not officially supported, and like all separation tools it works best on cleanly mixed material, but for a free one-click tool it is remarkably capable.
