Turn a long recording into separate files: cut at the times you mark, into a number of equal parts, or automatically at the pauses between songs or chapters. Download each part or all of them as a ZIP.

Three ways to split
| Mode | Good for |
|---|---|
| At times you mark | Chapters of a talk, songs of a live set, the questions of an interview |
| Into equal parts | Upload limits (for example 10-minute pieces), sharing a long lecture in sections |
| At silences | Records and tapes digitised in one go, voice notes with pauses between topics |
How silence detection works
The tool decodes the audio and measures its level every 20 milliseconds. Every stretch quieter than the threshold (default −40 dBFS) for at least the minimum length (default 0.7 s) becomes a cut, placed in the middle of the pause. Tick “Remove the silence” to drop the pauses completely.
- Too many parts? Lower the threshold (−50 dB) or make the minimum pause longer.
- Missing a split? Raise the threshold (−30 dB): noisy recordings are never fully silent.
Same quality as the original
When MP3 parts stay MP3 and M4A parts stay M4A, they are copied without re-encoding and cut on frame boundaries, so nothing is lost and the parts add up to the full length. WAV stays uncompressed. Everything runs in your browser; nothing is uploaded. To join files instead, use Merge audio.

Frequently asked questions
Can I split an MP3 without losing quality?
Yes. Keep MP3 as the output and the frames are copied unchanged into each part.
How do I split a recording into songs automatically?
Choose “At silences”. The default settings find the gaps between most songs; adjust the threshold if there are too many or too few parts.
How many parts can I make?
Up to 200. They download as one ZIP, or can be sent together with a link.
Does it work on a phone?
Yes, in Safari on iPhone and Chrome on Android. Splitting at silences decodes the whole file first, which takes a little longer on phones.
Is my audio uploaded?
No. It is split on your device.
