Quick answer: To split audio by silence, open the recording, keep the threshold at −40 dB and the shortest pause at 0.7 seconds, and press Split at silences. Every pause longer than that starts a new file, and you can remove the silence between parts. Parts in the input's format are copied without re-encoding. Nothing is uploaded.
A digitised record, a concert or a set of voice memos in one long file? Let the tool find the pauses and cut the recording into separate tracks for you.

Tuning the detection
Two settings decide where the cuts go:
| Recording | Silence is quieter than | Shortest pause |
|---|---|---|
| Vinyl or cassette with surface noise | −30 dB | 1.5 to 2 seconds |
| Music album or live set | −40 dB | 1 to 2 seconds |
| Speech, dictation, lessons | −40 dB | 0.7 to 1 second |
| Clean studio or digital audio | −50 to −60 dB | 0.5 seconds |
Too many parts? Make the shortest pause longer. Too few? Raise the threshold (−30 dB) so noisier gaps count as silence.
Songs with quiet passages
A song that fades to near silence in the middle can be split in two. Set the shortest pause longer than any quiet passage, typically 2 seconds for albums, and the gaps between tracks will still be found. For full control, switch the Split setting to At times I mark and place the cuts yourself.
Quality and formats
Parts saved in the same format as the input (MP3 to MP3, AAC to M4A) are copied without re-encoding; other combinations are decoded and encoded. Detection runs on the decoded sound in your browser, so long files take a little while to analyse.
