AI Vocal Remover and Stem Splitter

Stem separation pulls a finished mix apart into its instruments. Singers use it to get a karaoke track, DJs and producers to get an acapella for a remix, musicians to practise against the band with their own part taken out, and video creators to get a clean vocal. Autunes Stems splits a song into six standard parts in one go.

It works on songs you make on Autunes and on recordings you upload, which makes it useful for your own band's mixes, a singer's old demos or a track you have the rights to rework.

Removing the vocal gives you five instrument stems. Drop all five into any free audio editor or phone app and export them together, and you have the instrumental. Keep the vocal stem alone and you have the acapella. Leave out only the guitar or the piano and you have a practice track for that instrument.

For singing along with the words on screen, Autunes Lyric Video has a Karaoke style that times each line to the song, and the Karaoke section scores you as you sing over Autunes songs.

AI separation is very good on clean modern mixes and less perfect on old, noisy or heavily reverberant recordings, where a little of one instrument can bleed into another. Songs made with the fast engine can also come out rough; songs made on XL separate most cleanly.

Separation does not change who owns the song. Splitting a film song for practice at home is one thing; publishing its karaoke track or acapella needs the rights holder's permission. That is why uploads ask you to confirm your rights.
