What do you want to do?

Import audio, arrange and fade clips on a multitrack timeline, then export a lossless WAV.

Edit audio with a real multitrack timeline — import clips, arrange and trim them, split at the playhead, add fades, balance the mix, and export a WAV. There's no sign-up and nothing is ever uploaded to a server.

A real multitrack mixer

Stack clips on separate tracks and mix them exactly how you want. Drag clips to reposition them, grab an edge to trim, split at the playhead, and shape each clip with fade in, fade out and per-clip gain.

  • Unlimited audio tracks
  • Drag to move, handles to trim
  • Per-clip fades and gain, per-track volume, mute & solo

Private, lossless, offline

Every file is decoded and mixed at full resolution, so the export matches what you hear on the timeline. The final mix is rendered to a lossless WAV, and the tool keeps working offline once the page has loaded.
