LoopBook: Practice Clips

About this app

Slow down a tricky passage, loop it, and get it right — built for musicians and music students learning by ear.

LoopBook lets you import your own audio and mark a practice loop: set a start and end point, slow the playback down without changing pitch, shift the pitch if you need to, and loop it for as long as it takes to nail it. Each track can hold multiple named loops, so you can save several practice sections from the same recording — a tricky bridge, a solo, a chord change — and jump straight back to any of them.

Add notes to remind yourself what to focus on, attach a chart or lyric sheet, and share the whole thing — track, loops, notes, and attachments — as one file with a teacher or bandmate.

Free for up to 4 tracks, with unlimited loops on each one. LoopBook Pro removes that limit.

What’s new
