New in Acapo: find any song's key, move it to fit your voice, loop the hard part and record your own cover over the band.
Acapo takes a song you already own, lifts the voice out and hands you two clean tracks: the band and the vocals. Then it helps you actually sing it.
SING IT IN YOUR KEY
Acapo listens to the song on your iPhone, finds its key and tempo, and works out where the lead vocal sits. Tell it whether your voice is low, middle or high, and one tap moves the whole song into your range, without changing the speed.
RECORD YOUR COVER
Put on headphones, hit Sing and record yourself over the band. Balance your voice and the music, add a little room, nudge the sync, and keep the finished cover. Share it anywhere.
PRACTICE THE HARD PART
Mark A and B to loop a tricky line or solo. Slow the tempo down until it feels easy, keep the key where it is, then bring it back up.
KARAOKE OR ACAPELLA IN ONE TAP
Mute the voice for a karaoke track, mute the band for a clean acapella, or blend the two however you like. Save either track as its own file.
WORKS WITH YOUR OWN AUDIO
Bring songs from your music library, Files, the soundtrack of a video, or record a jam. Acapo does not search, stream or download music from the internet. Five original demo songs are included to try every feature straight away.
