Getting the wrap to land on the beat
The trick to a satisfying A-B loop is bar math: at 120 BPM a bar lasts two seconds, so selections of 4, 8, or 16 seconds wrap on the groove and anything else stumbles. Set A on a downbeat, use the length readout to aim for whole bars, and nudge B with the arrow keys until the handoff disappears. Your ears will tell you the exact frame.
Frequently asked questions
How do I loop one section of a song?
Load the file, drag across the waveform to set the A-B region, and press play. Playback cycles the region with a sample-accurate jump — nudge the edges with the arrow keys until the wrap lands on the beat.
Why does the loop feel like it stumbles?
The region probably isn't a whole number of bars. Move the end point until the groove hands off cleanly — the length readout helps: at 120 BPM a bar is 2.0 seconds, so 4 bars is 8.0.
Can I share my loop with someone?
The link carries your loop points and they carry the same file, yes — send both. Loop settings also autosave per song name on your device.
Is this good for language or lecture audio too?
Perfect for it — A-B repeat was born on language-lab tape decks. Drop any audio, not just music.
