Riftone vs Stem Splitter

Split any song into its parts and hear every instrument on its own — powered by AI. Riftone separates a track into 6 clean stems: vocals, drums, bass, guitar, piano, and other. Mute the drums to practice your part, drop the bass to play along, pull out the voice for a clean vocal, or rebuild the mix for a cover or remix. WHAT YOU CAN DO • Remove vocals, drums or bass from any song • Split into 6 stems and mute, solo or fade any instrument • Isolate the voice for covers, sampling and study • Shift pitch ±12 semitones without changing speed • Slow down or speed up and play along with the built-in metronome • Trim a section and export the mix or the separated stems IMPORT FROM ANYWHERE Add songs from your music library, Files, a link, the microphone, or a video in your camera roll. Try it instantly on the built-in demo tracks — no import needed. MADE FOR Guitarists, bassists, drummers, singers, teachers, producers and creators who want clean parts fast. Riftone Premium unlocks unlimited AI separation. Subscription auto-renews unless canceled at least 24 hours before the end of the period.
