Audio editor
Multiple tracks on a timeline, mute/solo, trims and local mix export.
100% in browser— No files or data are sent to a server. Everything runs on your device.
Build a professional timeline in your browser: import multiple audio files (or videos with audio), each on its own track, align clips in time, apply mute/solo, volume, fades and cuts, then export the final mix as WAV or MP3.
Ideal for combining narration and bed music, aligning takes, cleaning sections and preparing clips for podcasts or social — without installing a DAW.
Processing is 100% local. The Web Audio API decodes common formats; FFmpeg WebAssembly (jsDelivr CDN) loads on demand for harder formats and MP3 export. Up to 8 tracks per project.
Frequently asked questions
Can I open more than one file?
Yes. Each file becomes a track on the timeline. Use "Add tracks" or drop several files at once (maximum 8 tracks).
Are my files uploaded to the internet?
No. All editing happens in your browser. Only the FFmpeg core may be downloaded from the CDN on first MP3 export or when decoding non-native formats.
How do I move a clip in time?
Select the track and Shift+drag on the timeline, or adjust the "Start (s)" field in the sidebar.
What gets exported?
The mix of all audible tracks (respecting mute/solo and gains), as WAV or MP3.
Is there a size limit?
Up to 100 MB and 10 minutes per file. For best performance, prefer up to 5 minutes.
