Chapter 7 Working in the Waveform Editor 153

Scrubbing Audio Files in the Waveform Editor

You can also scrub the audio file in the Waveform Editor. Scrubbing the audio file lets

you hear the audio at the playhead position as you drag the playhead, so you can find

a particular sound or event in the audio file.

To scrub an audio file:

1 Press and hold the triangular part of the playhead.

2 While holding the playhead, drag left or right at the speed you want to scrub the

audio file.

Scrubbing is useful to help identify the part of an audio file that you want to edit. While

you are scrubbing an audio file, you can select the part of the file that you want to edit.

To make a selection while scrubbing:

m As you move the playhead, press and hold the Shift key.

Using the Timeline Controls in the Waveform Editor

You can use the Timeline controls, located at the lower-left corner of the Project

window, while working in the Waveform Editor. Some of these controls have slightly

different functions in the Waveform Editor than they do in the Timeline.

Â Master Envelopes button: You can show or hide the envelopes for the audio file.

Â Snap button: You can turn snap on or off in the Waveform Editor.

Â Snap To button: You can choose the Snap To value that the playhead and other items

snap to. In the Waveform Editor, the choices for snap are Ruler Ticks and Zero

Crossings.

Â Track Height control: Sets the height of the envelope rows when you show envelopes

in the Waveform Editor.
