Audio Editor

Multi-Track Mixing on a Timeline.

Lay music, voice and sound effects on separate tracks, trim and fade them, set the volume of each and export one audio file. The timeline editor does the mixing in this browser, so nothing is uploaded.

  • Several sound tracks side by side on one timeline
  • Cut, split, move and fade each sound
  • Volume that changes over time, with keyframes
  • Export as MP3, WAV, M4A or OGG

The video editor with a title selected: text styles on the left, the preview in the middle, text settings on the right and a timeline with text, video and music tracks below

When one sound has to sit on top of another, a single-purpose tool is not enough. The audio editor is the timeline editor of this site used for sound only: each file gets its own track, and what you hear is the mix of all of them.

How to use the Audio Editor tool

  1. Open the editor and import your sound files; each one lands on its own track.
  2. Drag sounds to place them, pull their ends to trim, split at the playhead and set volume and fades for each.
  3. Press Export and choose MP3, WAV, M4A or OGG.

Tips for the best result

  • Lower the music to about 20 to 30 percent while someone is speaking, using volume keyframes.
  • Save the project to a folder if you want to continue another day.

Frequently asked questions

Is this the same editor as the video editor?

Yes. It is one editor. With only sound files in a project, the audio formats are the ones to export.

How many tracks can I use?

As many as you need; a track is added whenever a sound is placed on a new row.
