Stop scrubbing for the gaps
Digitising a record side, chopping a sample session into one-shots, or breaking a recorded set into songs all come down to the same job: find every silence and cut there. Doing it by hand means scrubbing through the timeline; WAVR does it in a second and shows you where it will cut before anything happens.
The detector scans the audio in 10 ms windows. Anything below the threshold for at least the minimum gap counts as silence. Everything between those silences becomes a part, with 50 ms of breathing room kept on each side.
How to split a recording
- Add the recordingDrop the file. The editor opens and runs a first pass with −50 dB and a 1 second gap.
- Adjust and previewChange the settings and click Find silences. Parts are shaded on the waveform; play any of them to check.
- Create and exportClick Create files. Each part joins the queue as "name part 01"; convert them in one batch and Download all as a ZIP.
Settings that work
| Source | Threshold | Minimum gap |
|---|---|---|
| Vinyl or cassette rip | −40 dB | 1.5–2 s |
| Live set or DJ mix with gaps | −50 dB | 2 s |
| Drum hits, one-shots | −50 dB | 0.2 s |
| Podcast or lecture sections | −45 dB | 3 s |
Tip: if a quiet intro or breakdown gets split off, lengthen the gap rather than lowering the threshold.
Splitting questions
What threshold should I use?
Start at −50 dB. For vinyl or tape with surface noise between tracks, try −40 dB. For clean digital recordings, −60 dB catches quieter gaps.
Why did a quiet passage get split?
The gap setting is too short or the threshold too high. Raise the minimum gap to 2 seconds, or lower the threshold, so breakdowns and quiet intros stay attached.
Is any silence kept?
Yes, 50 ms at each edge so notes don't start or end abruptly. Parts shorter than half a second are skipped.
Can I split a long file on my phone?
Yes, but each file is decoded in full first, so very long recordings need plenty of free memory. An hour of stereo audio at 44.1 kHz takes about 1.3 GB once decoded.
