Audio Editing Aids
The Avid system provides audio scrub features and waveform plots
specifically designed for frame-accurate cueing, marking, and editing
of audio. You can use these features any time during editing or while
making adjustments with the audio tools.
Using Audio Scrub
The term audio scrub originated in the film industry. It describes the
process of “scrubbing” a magnetic audiotape across the playback
heads to monitor a portion of sound. This process helps isolate por-
tions of audio to accurately mark edit points, or to analyze transitions
for careful trimming.
Smooth Scrub Versus Digital Scrub
You have two options for scrubbing audio in either the sequence or the
source material:
• Smooth audio scrub mimics the variable pitch playback of tradi-
tional analog tape.
• Digital audio scrub takes advantage of the digital environment by
sampling incoming frames, outgoing frames, or both at normal
pitch and playback rate.
Each type of scrub has its advantages:
• Smooth scrub makes it easier to examine sound at varying speeds.
• Digital scrub allows you to focus quickly on individual bits of
incoming or outgoing audio for frame-accurate edits and adjust-
ments.
Try both types of scrub and see which one works better in different sit-
uations.
