About the Audio Silence Splitter
A long recording often holds many separate parts: songs digitised from a tape, several voice notes recorded in a row, questions and answers in an interview, or the parts of a dictation. Cutting them apart by hand is slow. This tool finds the silences for you and splits the recording at each one. Choose the level that counts as silence, how long a gap must be to split, how much sound to keep around each piece and the shortest piece worth keeping. You get a list of the pieces with their start and end times, can listen to any of them and download each as a WAV file or all of them together in a ZIP. The audio is processed in your browser and never uploaded.

Setting it up
Start with a level of -45 dB and a gap of 1 second. Press Find the pieces, then look at the list. For a tape or vinyl digitisation, the noise between songs is often louder than true silence, so raise the level to about -35 dB. For a lecture with many short pauses, use a gap of two or three seconds so that you only split at real breaks.
Use the shortest piece setting to drop tiny bits, such as a cough or a click, that would otherwise become their own tiny files.
Digitised tapes usually have hiss in the gaps, which sits well above digital silence, so a level of -35 or even -30 dB is common. Interviews recorded in a quiet room may need -55 dB. If the first try gives pieces that cut off the start of words, increase the padding; if pieces contain a long tail of silence, reduce it.
Typical uses
- Split a digitised tape or record into songs.
- Separate a series of voice notes.
- Cut an interview into answers.
- Divide a dictation into sentences or sections.
- Break a long meeting recording at the pauses.

Frequently asked questions
How does it decide where to split?
It looks for stretches that stay quieter than your chosen level for at least the gap length. The sound between two such stretches becomes one piece.
Why do I get too many pieces?
Short pauses inside speech are being treated as silence. Make the gap longer (for example 2 seconds) or lower the silence level.
Why do I get just one piece?
No gap was long or quiet enough. Raise the level toward -35 dB or shorten the gap length.
What does the padding do?
It adds a short amount of sound before and after each piece so the start and end do not feel cut off.
Can I split a whole album?
Yes, if the songs are separated by silences. Songs that run into each other without a gap cannot be found this way.
How many pieces can it make?
Up to 300 at once. If there would be more, the tool asks you to change the settings.
Is my recording uploaded?
No.
