A complete audio editor.Right in your browser.
Multitrack timeline, recording, fades and precise cuts, with export to WAV or MP3. Everything runs on your device, so nothing is ever uploaded.
Private by design
Decoding, editing and exporting happen locally. Your audio never touches a server: no upload, no waiting, no privacy trade-off.
A real multitrack timeline
Unlimited tracks, drag-and-drop clips, snapping, fades and crossfades on a fast canvas timeline that stays smooth as your project grows.
Record, mix, export
Record from your microphone, balance levels with per-track volume and meters, then export your mix to WAV or MP3 in seconds.
Popular tools

Cut Audio Online

Drop any audio your browser can play and export it as MP3 (128–320 kbps) or uncompressed WAV, all locally and with no upload.

Sound effects
A whoosh is one drag away
A shelf of built-in effects — transitions, impacts, cinematic, interface, atmosphere and foley — lives in the editor's toolbar. Audition one, then drop it on a track. What lands is an ordinary clip: move it, trim it, fade it, export it.
- Nothing to download: every effect is generated on your device, so they work offline.
- Bring your own. Imported effects stay in your browser and are there in your next project.
- Search by name, by category, or by the word you already use for it.
