Applies to a drop on an existing track. A drop on empty space always makes a new track with its clip at bar 1.

Space plays. Enter or Home returns the playhead to the start. Shift+Home moves the selected clip to the project start. R records onto every armed track, Shift+R arms the selected track. Arrow up and down select a track when no clip is selected, Escape clears the selection. Ctrl+C copies the selected clip, Ctrl+V pastes it onto the selected track at the playhead. X opens the mixer, L opens the sound library. Ctrl+Z undoes, Ctrl+Shift+Z redoes, Delete or Backspace removes the selected clip, or the selected track when no clip is selected. Ctrl+D duplicates a clip. Shift+F switches full-window DAW mode on and off, F fills the whole screen and Escape leaves fullscreen without leaving DAW mode. Clicking an empty grid row adds a track. Hold Alt while dragging to ignore the grid. Ctrl and the wheel zooms.

Selected clip

Select a clip on the timeline to trim, split, duplicate or fade it.

Export mix

Render the mix first, then choose a format.

The mix is rendered by the same graph that plays back, so the exported file is what you heard.

Format

MP3 is not offered: every JavaScript MP3 encoder is GPL/LGPL licensed and no browser exposes one. M4A plays everywhere MP3 does, including QuickTime and iPhone.

About this tool

SKELETUNE STUDIO is a free multitrack recording studio and audio editor that runs entirely in your browser. Drop clips onto tracks, line them up on a tempo grid, trim their edges, overlap them for a crossfade, then balance the tracks with level and pan and render the mix to WAV, M4A or Opus.

Files are decoded once in your browser, cached by content hash and referenced from your arrangement, so the same file used ten times still only takes memory once. The arrangement itself is a few kilobytes of JSON, saved locally as you work.

How it works

  1. 01

    Drop clips onto tracks

    Drag audio onto a track lane, or use Import clip. Files already analysed elsewhere in SKELETUNE open from the cache with no second decode.

  2. 02

    Arrange on the grid

    Move clips with grid snapping, drag their edges to trim, split at the playhead, duplicate, and overlap two clips to crossfade them.

  3. 03

    Mix and export

    Set level, pan, mute and solo per track, loop a section while you work, then render the mix and export it in your format of choice.
