Slow down a tricky passage, loop it, and get it right. LoopBook is a music practice tool for musicians who want to work on difficult sections of songs, solos, lessons, and recordings. Import your own audio or video and create precise A/B practice loops. Set the start and end points, slow down the music without changing pitch, shift the pitch when you need to, and repeat a section for as long as it takes to nail it. Each track can contain multiple named loops, so you can keep all the sections you're working on together — a tricky bridge, solo, chord change, bass line, or anything else you want to practise. Jump straight back to any saved section whenever you practise. KEEP YOUR PRACTICE ORGANISED LoopBook is more than an audio looper. Build a library of the music you're working on, with your loops, notes and practice materials all kept together. Add notes to remind yourself what to focus on and attach a chart, sheet music, lyric sheet or other reference material. SHARE WITH TEACHERS AND BANDMATES Share a complete LoopBook track — including the audio, practice loops, notes and attachments — as one file. It's ideal for music teachers sending exercises or tricky passages to students, or musicians sharing practice material with bandmates. FEATURES • A/B repeat and precise practice loops • Slow down music without changing pitch • Pitch shifting • Multiple named loops per track • Audio and video • Practice notes • Attach charts, sheet music and PDFs • Share complete practice tracks • Organise your practice library Free for up to 4 tracks, with unlimited loops on each one. LoopBook Pro removes that limit.
