Song Practice: Slow Down Music

Slow any song down without changing its pitch. Loop the bar you keep missing. Hear the bass on its own. Any track becomes something you can actually learn from.

Built for musicians working songs out by ear.

PRACTICE AT YOUR PACE
- Play anywhere from 25% to 200% speed, with no pitch drift
- Loop any section and repeat it until your hands know it
- Save your loops and pick up where you left off
- Shift the key up or down 12 semitones to suit your voice or instrument
- Automatic BPM detection and a built in metronome

HEAR EVERY PART
- AI separation into vocals, bass, drums and everything else
- Solo the part you are learning, or mute it and play it yourself
- Separation runs on your device

KNOW THE SONG BEFORE YOU PLAY IT (iOS 27)
- Sections found for you: intro, verse, chorus, bridge, solo and outro
- Jump straight to the chorus or loop the solo with one tap
- Skip from section to section right from the player
- Key detection for every song
- A metronome that follows the song's real beats, even when the tempo drifts
- A timeline of beats, bars, phrases, key changes, loudness and where each instrument plays
- Analysis runs on your device and happens once per song

LEARN THE WORDS
- AI lyric transcription
- Sing along to lyrics that follow the track

TAKE THE WORK WITH YOU
- Export the full mix at your chosen speed and key
- Export any part as WAV, AIFF, CAF or M4A
- MIDI export for any separated part
- Export the whole song, or just the section you looped

BRING IN MUSIC FROM ANYWHERE
- Files, iCloud Drive and other cloud storage
- Your music library
- Videos from Photos
- Record a song playing in the room
- Paste a public link
- MP3, WAV, M4A and FLAC supported

Learning a solo, transcribing by ear, rehearsing with your band or building a backing track: every part of the song is yours to control.
