Merge audio files into one seamless track
Line up intros, interviews and music on a multitrack timeline, blend them with crossfades, and export a single file.
How it works
Import everything
Drop all your files at once. Each one lands on its own track, ready to arrange.
Arrange and blend
Drag clips into order with snapping, overlap them for automatic crossfades, and balance levels per track.
Export one file
Render the whole timeline to a single WAV or MP3, exactly as you hear it.
Why Ressoara
Real crossfades
Overlapping clips blend smoothly, with no hard jumps between songs or segments.
Mix while you merge
Per-track volume, mute and solo let you balance voices and music before exporting.
Any mix of formats
Combine an MP3 with a WAV and an M4A in the same project. Formats are unified on export.
Frequently asked questions
Yes. Each file sits on its own track with a volume slider, mute and solo, so you can balance everything before exporting.
No. Every file you drop is decoded locally and the final mix is rendered on your own machine. Joining ten files works like joining two: no upload, no queue, and no size cap beyond your own memory.
Anything your browser can decode: MP3, WAV, OGG, M4A/AAC, FLAC and WebM. Exports go out as WAV, MP3, M4A/AAC, OGG or FLAC.
