Practice tools

Every part of the song, yours to control

Learning a solo, transcribing by ear, rehearsing with your band or building a backing track: Song Practice turns any recording into something you can actually learn from.

Slowing a song to 76% speed in Song Practice while the pitch stays untouched

Slow down music

Drop the tempo.
Keep every note.

Drop the tempo as low as you need and every note stays true to the record. Speed is shown as a share of the song's own tempo, because that is how you think about it: take it at 75%, then nudge it back up.

Speed from 25% to 200%, with no pitch drift
Tempo steps of 5% of the original BPM, so 120 → 90 is a few taps
Metronome that locks to the song's own tempo

A-B loop

Loop the bar you
keep missing

Set A and B once and the passage repeats at your practice tempo until your hands know it. Markers snap to bars and can be nudged a beat at a time, so the loop is exactly the phrase you are working on.

Loops keep your slowed-down tempo

How it works

From first listen to playing along

Four steps. Song Practice does the analysis while you tune up.

Import

Bring in a song from Files, your iTunes library, Photos, cloud storage, or paste a link. Audio and video both work.

Slow & loop

Drop the speed, set A and B around the hard passage, and let it repeat. The key never moves unless you move it.

Isolate

Split the song into stems. Solo the bass to hear every note, or mute your part and play in its place.

Take it with you

Export any stem as WAV, M4A or MIDI, for the whole song or only your loop, and drop it into your DAW or rehearsal set.

Also inside

A practice room in your pocket

Metronome that follows the song

The click locks to the track's detected tempo and stays locked when you slow it down, so you always practise on the grid.

Change the key

Shift up or down by as much as 12 semitones without touching the tempo. Match your capo, a drop tuning or your vocal range.

Audio to MIDI

Turn any separated stem into MIDI and open the notes in GarageBand, Logic or any notation app.

Lossless export

WAV or M4A for any stem, the full mix, or just the section you looped. Ready for a backing track or a DAW session.

Import from anywhere

Files, iTunes, Photos, iCloud Drive and other cloud storage, or paste a link. Video soundtracks work too.

Private by design

Stem separation and song analysis run on your device. The song you are learning never has to leave your phone to be split.

Who it's for

Made for your instrument

Whatever you play, the part you need is in the song. Song Practice gets it out.

Guitarists

Slow down solos, loop the lick, and mute the guitar to play the part over the band.

FAQ

Frequently asked questions

Can I slow down a song without changing the pitch?

Yes. Song Practice changes tempo and pitch independently. Take a song anywhere from 25% to 200% of its original speed and it stays in the original key, so a 128 BPM track at 76% plays at 97 BPM and still sounds in C♯. Learn more →

Is Song Practice free?

Song Practice is free to download from the App Store and you can start practising straight away. Slowing down, looping and changing key are free, and you get a few free stem separations to try. Song Practice Pro unlocks unlimited separations and lyrics, WAV, M4A and MIDI export, and removes ads. Compare slow downer apps →

How do I remove the vocals from a song?

Import the song, let Song Practice split it into stems, then open Mix and tap the Karaoke quick mix. The vocal stem is muted and the band keeps playing. You can export that instrumental as a WAV or M4A file. Learn more →

Which parts can Song Practice separate?

Vocals, drums, bass and everything else. Each stem has its own level, so you can solo the part you are learning, mute it and play it yourself, or use quick mixes such as Karaoke, Vocals only, No drums and Rhythm. Learn more →

Does stem separation upload my music?

No. Stem separation runs on your iPhone or iPad, so the song you import stays on your device while it is split.

How do I loop one part of a song?

Set an A marker at the start of the passage and a B marker at the end. Song Practice repeats that section at whatever tempo you have chosen, and you can nudge A and B by a beat until the loop is exactly the bars you need. Learn more →

Can Song Practice change the key of a song?

Yes. Shift the key up or down by as much as 12 semitones without changing the tempo, to fit your vocal range, a capo position or a tuned-down instrument. Learn more →

Yes. Song Practice transcribes lyrics with AI in many languages and highlights each line as the track plays, so you can sing along or learn the words. Learn more →
