Basic Audio Editing

Editing Audio

Clips can be cut, copied, pasted, and deleted with Edit menu commands, or moved and copied with

drag-and-drop techniques. For more information, see “Arranging and editing” on page 287.

Audio Scaling

Audio scaling is the increase or decrease in the size (scale) of the waveform in a track or bus. Audio

scaling allows you to make detailed edits by zooming in on the parts of the waveform closest to the

zero crossing (silence) while preserving the track or bus size. By showing just the quietest parts of a

clip, you can make very precise edits. You can also zoom out on the waveform.

You can change the audio scale using keyboard shortcuts or the Audio Scale Ruler.

The Audio Scale Ruler is located in the vertical splitter bar between the Clips pane and the Track

pane.

There are three display options in the Audio Scale Ruler:

• Percentage. Shows audio scaling by percentage. For example, if the highest percentage in the

Audio Scale Ruler reads 2.0%, then only the parts of the waveform which are within 2% of the

zero crossing appear in the clip.

• dB. Shows audio scaling by dB. For example, if the highest dB in the Audio Scaling Ruler reads

-36, then only the parts of the waveform which are 36 dB below 0 dB appear in the clip.

• Zoom Factor. Shows audio scaling by a factor. For example, if the Zoom Factor reads 10, then

Note: The Audio Scale Ruler does not appear on multi-layered tracks.
