a player for the players.
An audio player made for musicians.
Map the song in a minute.
Mark the song's sections (verse, chorus, C part). Each gets its own colour on the waveform.
And each one's a spot you can jump straight to, loop on repeat, and come back to next time you open the song.
Slow it down.
Half speed, quarter speed, anything in between. Pitch stays put, so the song still sounds like the song.
Change the key.
Move the song up or down by semitones. No chipmunks, no monster voice. Drop a half-step to sing it, or shift it onto your instrument's tuning.
Loop any part.
Drag a bracket across any part of the song. Loops snap to bars, so when it repeats the beat keeps going. No awkward jump backs.
Split into stems.
Pull vocals, drums, bass and other out of any track. Mute the singer or solo the bass line, or just turn down the drums a little. Splits save per song.
Click in time.
A built-in metronome locked to the song's beat, accented on the downbeat, so you always know where bar one is.
Knows your song.
Add a track and Lio works out its key, tempo, and time signature on the spot. If it ever reads one wrong, set it right yourself.
A rehearsal tape, split into songs.
Drop in one long recording (a whole rehearsal, a practice session) and Lio finds the breaks and splits it into separate songs.
Nudge any split that's off, then they land as a setlist: each take its own track, ready to loop and slow down.
Your library, your sets.
Import a folder of songs, or pull from your Music app library. Every track lands with its key, tempo, and beats worked out automatically on your Mac, the moment it's added.
Browse by Songs, Recents, Setlists, or your own Tags. Long lists sort A→Z (Hebrew too), so any song is a glance away. Pull tracks into a setlist, reorder with a drag, switch sets in one click.
Send & receive setlists.
Hand a song (or an entire setlist) to another Lio user. It lands as an imported setlist, your loops, sections, detected key, and edits all intact.
Or save a copy to share however you like: AirDrop, email, a shared drive. And if a song shows up without its audio file, Lio marks it "No audio" and lets you point at the file on your Mac.
Record from your Mac.
If you can hear it on your Mac, Lio can record it. Pick the app that's playing, watch the level meter, and hit record. What you capture lands as a brand-new song, with its key and tempo detected automatically. Free covers three a month; Pro lifts the cap.
Questions? We've got answers.
Still stuck? Email support@lioplayer.com.
Is there a free version?
Yes, and it's a real one, not a teaser. Download it and you can open any song, slow it down, and loop sections for as long as you like. Pro adds key changing, stem separation, the section editor, and the song library + setlists.
How much is Pro?
$36 a year, or $126 once and you're done. Both cover Pro on up to 2 Macs.
Does it work on Intel Macs?
Lio is built for Apple Silicon Macs (M1 and later) running macOS 14 Sonoma or newer. Intel Macs aren't supported.
Where do my files go?
Nowhere. The app runs entirely on your Mac, stem separation included. Getting Pro takes a quick sign-in with Apple or email; after that it works offline.
What formats does it read?
mp3, m4a, wav, flac, aac, and aiff. Drag a file onto the window or import a folder. Apple Music subscription tracks (DRM) aren't supported.
What can I record from?
If you can hear it on your Mac, Lio can record it: any app, any website. Pick the one that's playing, hit record, and it lands as a new song with its key and tempo detected. It records just that one app, so notifications and other sounds stay out. You're responsible for having the right to use what you record. Free covers three recordings a month; Pro removes the cap.
Refunds?
Not for you? You're covered by a 14-day money-back guarantee. Email support@lioplayer.com. Checkout and refunds run through Lemon Squeezy, no hassle.
