Pro Audio applies the specified equalization to the selected audio.

Advanced Audio Processing

Pro Audio provides a number of advanced audio processing commands
for power users. Among these are commands to remove silent sections of
audio from the data, to extract timing information, to detect pitch, and
to apply parametric equalization, fades/envelopes, and crossfades.

Removing Silence

The Remove Silence command detects sections of audio that fall below
a given loudness threshold, and replaces those sections with absolute
silence. Remove Silence gives you the option of actually deleting the
silent sections from the selected audio events, splitting long audio events
into a greater number of shorter audio events.
Pro Audio treats passages of absolute silence intelligently. It doesnÕt
store stretches of silence on disk, and thereby conserves disk space.
During a passage of absolute silence, Pro Audio sends no signal to the
digital output port; this results in cleaner audio playback. Remove
Silence is great for cleaning up your Þnal audio mix, because it can
mute all audio tracks in which the live performers were Òlaying out.Ó
Using Remove Silence to split long audio events into smaller ones
opens a variety of creative possibilities. For example, suppose youÕve
found an awesome 4-bar drum loop, but itÕs at the wrong tempo for the
song youÕre working on. With Remove Silence, you can separate each
beat into its own event, and then rework the loop into your song beat-by-
beat.
The parameters in the Remove Silence dialog box are used to specify
exactly what you mean by silence. More precisely, Remove Silence
employs what is called a digital noise gate. The gate is a type of Þlter, it
passes data through, or stops it from passing through, according to
certain criteria. Parameters in the dialog box specify the conditions
under which the gate is opened and under which it closes again.
