Using Audio 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 traditional analog tape

• Digital audio scrub — Takes advantage of the digital environment by sampling incoming

frames, outgoing frames, or both at a normal pitch and playback rate

Digital audio scrub enables you to sample selected frames of incoming or outgoing audio as you

move through the footage, without a change in pitch or speed. Digital scrub has the following

unique characteristics:

• The frames of audio you hear are always at your point of destination. For example, if you

step forward 10 frames (8 frames for 24p), you hear a selected number of audio frames from

a point behind the position indicator (outgoing frames) to a point in front of the position

indicator (incoming frames) as it reaches the new destination point.

• Digital scrub samples audio in a forward playback direction. Whether you step backward or

forward through the material, you hear the same audio sampling at each destination frame.

Each type of scrub has its advantages:

• Smooth scrub makes it easier to examine sound at varying speeds.

• Digital scrub lets you focus quickly on individual bits of incoming or outgoing audio for

frame-accurate edits and adjustments.

If you attach a 002 to Avid input/output hardware, you cannot hear the results of audio

scrubbing.
