# Split Audio Automatically at Silences

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.

**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.

## How to use it

1. Choose the long recording.
2. Keep −40 dB and 0.7 seconds, or adjust them: see the table below.
3. Tick Remove the silence between parts if you want tight tracks.
4. Press Split at silences, check the parts, and download them as a ZIP.

## 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.
