Map the sound to a cause
| What you hear | Likely cause | First fix |
|---|---|---|
| Sharp tick / pop | Amplitude or phase step at the join | Level splice / pick matched ends |
| Short hole / hiccup | Silence padding at head or tail | Trim zero regions |
| Whoosh that “restarts” | Reverb/delay tail cut off | Loop where wash is steady |
| Pitchy blip | Bad crossfade or time-stretch at the edge | Undo stretch; re-export clean |
How to listen so you are not guessing
Export (or bounce) a test that is only the last second + the first second of the file, then loop that tiny clip. If the bug is real, you will hear it every two seconds. Fixing “the whole mix” while the bug lives in 64 samples at the edge wastes time.
Fast path vs surgical path
Fast: drop the file into Loop Music and let it search for a splice and level the seam (~20 seconds). Best for beds and practice loops.
Surgical: in a DAW, zoom to the sample level, align zero-crossings, match RMS on both sides of the cut, export WAV. Best when the loop must stay musically exact (one-bar drums, keyed sound design).
After the file is clean, stop re-breaking it
Editors that trim audio ends (CapCut, Premiere, Resolve) can put the click back. If a host keeps adding the tick, check whether the timeline still contains your seamless file or a re-trimmed derivative. See also CapCut and OBS / Twitch.
