How to cut mistakes out of an audio recording

Most recordings need a few small fixes: a false start, a cough, a phone buzzing, or a tangent you would rather not share. You can remove any number of sections and keep the rest joined smoothly in the cut out sections tool.

Plan before you cut

Listen through once and note the times of each problem. A simple list such as "0:42 cough, 1:15–1:31 false start, 3:02 phone" saves time. Remember the tool uses seconds, so 1:15 is 75.

Making the cuts

  1. Open the recording and find the first problem on the waveform. Speech shows as tall shapes; pauses are flat.
  2. Drag across it. Start and end in a quiet moment between words if you can.
  3. Press Hear in the cut list to play the original one second either side of the cut, and adjust the times if a word is clipped.
  4. Repeat for each problem, then press Preview result to hear the edited version from the start.
  5. Download as WAV if you will edit further, or MP3 when you are finished.

Where to place a cut

Avoiding clicks and jumps

The tool adds a very short fade either side of every join, which prevents clicks. A join can still sound abrupt if background sound changes, for example if music or traffic is audible on one side of the cut but not the other. Cutting during a pause, where the background is steady, gives the smoothest result.
