Split Audio
Split audio into equal parts, fixed lengths, at chosen times, or wherever there is silence.
Free, no uploads, no sign-up. Runs 100% in your browser.
How Split Audio works
The audio is decoded with the Web Audio API, cut into parts and encoded with ffmpeg. Silence detection runs on the decoded samples.
Input: MP3, WAV, M4A, OGG, FLAC, AAC, MP4, WEBM. Output: MP3, M4A, OGG, WAV, FLAC, ZIP.
How to use Split Audio
- Drop a file.
- Choose how to split and check the markers on the waveform.
- Split and download the parts or a ZIP.
Tips
- WAV is lossless but large; MP3/AAC/OGG are compact for sharing.
- Engines load on first use and are cached afterwards.
Split Audio FAQ
- Are my files uploaded?
- No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
- Is it free? Are there limits or watermarks?
- Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
- Does it work offline?
- Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
