Loop an audio file
and save the repeats as one WAV.

Cut one clean phrase

Open the recording in the audio cutter and use Start (seconds) and End (seconds) to select the phrase. For music, count whole bars and put both ends on the same beat, for example the downbeat of bar 1 and the downbeat of bar 5.

Keep Fade each edge (seconds) at 0 so the volume doesn’t dip at every repeat, then press Play and save it with Download WAV. Hang on to the original recording in case the loop comes back a touch early or late and you need to recut it.

Join the copies into one longer file

1. Copy the clip on your device. Each file plays once in the joiner, so duplicate your saved phrase in your file manager and name the copies phrase-01.wav, phrase-02.wav, phrase-03.wav and so on.
2. Select all the copies. Open the audio joiner, select Choose files and pick every copy at once. You can join up to 20 files and 20 minutes of audio in total.
3. Count the list. Every entry is one repeat, so five entries means you’ll hear the phrase five times. Use Up and Down if you’ve slipped a different phrase in and want it somewhere else.
4. Leave the crossfade at 0. With Crossfade at each join (seconds) at 0, every repeat keeps the exact length of your phrase, so the beat stays steady.
5. Listen, then save. Press Play, listen through a few joins and click Download WAV once the phrase comes back right on time.

Listen to the join, not just the phrase

Count through the last bar and into the next repeat. A doubled beat means the clip runs a little past where it should end. If the loop comes back too soon, it ends early. Fix the cut in the original, then make fresh copies from the corrected clip.

A crossfade overlaps the end of each copy with the start of the next, which shortens the file and nudges the timing. That can smooth out a sustained pad or ambient texture, but a rhythmic phrase almost always needs an accurate cut more than an overlap.

Make it as long as you need

With the crossfade at 0, the numbers are easy: three copies of a 20-second phrase give you a 60-second file. The joiner saves it as joined-audio.wav, so rename it with the phrase and the repeat count, like “bridge-x6.wav,” and you’ll find it fast at rehearsal. Keep the single-phrase WAV too. It’s your starting point next time you want a longer or shorter loop.
