App Profile: Ruffio: AI Stem Generator

Ruffio – Backing Track Maker, Karaoke App, Music Stem Splitter, and AI Music Practice Tool

Ruffio is the all-in-one music app that lets you remove vocals from songs, isolate instruments, and create custom multitrack backing tracks using advanced AI audio separation—right on your iPhone or iPad. Whether you're a singer, musician, student, producer, DJ, or music lover, Ruffio helps you unlock the full potential of any track.

Using powerful machine learning, Ruffio separates songs into stems—vocals, drums, bass, and accompaniment—so you can mute, solo, or adjust individual instruments. Create karaoke versions, practice your instrument, or hear the mix like never before.
