Riffloop is a stem splitter and vocal remover for musicians. It pulls a song apart so you can hear the part you are trying to learn, then loop it and slow it down. Add a song and Riffloop splits it into vocals, drums, bass, guitar, piano and everything else. Mute the guitar and play it yourself. Remove the vocals and sing karaoke. Solo the bass and work out what it is doing. Separation runs on your iPhone, so your audio is never uploaded. YOUR FIRST SONG IS FREE, IN FULL Your first split is the whole song, every part, at no cost. Hear what Riffloop does with your own music before you decide anything.

Take any song and split it into separate instruments: vocals, drums, bass, guitar, piano, and everything else. Then use the built-in mixer to mute the part you play and practice with a real band behind you. REMOVE VOCALS OR ANY INSTRUMENT Pull a fader down and the singer is gone. Solo the drums to learn the groove. Mute the bass to play it yourself. Every instrument has its own fader from 0 to 150%. TWO WAYS TO SPLIT • Six stems: vocals, drums, bass, guitar, piano, and other • Vocals only: separate the voice from the backing track for karaoke and acapellas PRACTICE TOOLS • Trim the song to the part you're learning and repeat it • Slow it down to 50% or speed it up without changing the key • Transpose up to 12 semitones without changing the tempo, for the whole song or a single instrument • A metronome that detects the BPM from the drums and clicks in time • Skip 10 seconds back or forward with one tap RECORD YOURSELF Sing or play over the track. Your recording becomes a new lane, synced with the song, with its own fader and trim controls. EXPORT Save the whole mix or a single stem as an audio file and share it anywhere. BRING MUSIC FROM ANYWHERE Import audio files, videos, videos from Photos, direct links, or recordings made right in the app. Five demo songs are already split so you can start in seconds.
