Cut audio online, down to the millisecond
Trim silence, remove mistakes or split a long take on a real multitrack timeline, not a toy trimmer. Free, and your audio never leaves your device.
How it works
Drop your file
Drag any MP3, WAV, OGG or M4A into the editor. The waveform appears in seconds. There is no upload bar, because there is no upload.
Cut with precision
Zoom into the waveform, press B to split at the exact spot, then delete or drag the parts around. Snapping keeps cuts clean.
Export instantly
Download the result as WAV or MP3. Everything renders on your device, faster than real time.
Why Ressoara
Millisecond precision
Zoom deep into the waveform and place cuts exactly where they belong, with snap to grid, clip edges and the playhead.
Non-destructive editing
Every cut is a reference, not a copy: your original file is never modified, and every action has undo.
No upload, no queue
Most sites push your audio through a server. Ressoara runs entirely in your browser, so a 100 MB file is ready in seconds.
Frequently asked questions
Yes. The full editor is free and supported by ads: no watermark, no trial limits, no locked exports.
No. The file is decoded inside your browser and the cut is a non-destructive edit on the timeline, so the original on your disk is never touched and nothing is sent anywhere.
Anything your browser can decode: MP3, WAV, OGG, M4A/AAC, FLAC and WebM. Exports go out as WAV, MP3, M4A/AAC, OGG or FLAC.
