Cut one audio file into multiple tracks — automatically at silences or by placing your own markers. Runs entirely in your browser, so nothing is ever uploaded.
Open the Audio Splitter
Go to the DefyAudio Audio Splitter — it runs right in your browser, with nothing to install.

Drag and drop or browse for any MP3, WAV, FLAC, OGG or M4A file — a long recording, a vinyl rip, a DJ mix or a podcast.

Download all as zip
Preview each segment, then download them individually or as a single zip.
An audio splitter takes one long file and cuts it into several separate tracks. It's the fastest way to break a vinyl or cassette rip into individual songs, chop a DJ mix or live set into tracks, or divide a long recording or podcast into chapters — each exported as its own file.
DefyAudio's splitter can find the natural break points for you by detecting silences, or you can place cut markers by hand on the waveform for full control. Because it runs on-device with WebAssembly, even long files and private recordings stay on your computer — nothing is uploaded.
Open DefyAudio's Audio Splitter, add your file, let it detect silences or place cut markers by hand, choose a format, and click Split audio. Each part downloads separately — free with an account.
