Advanced Audio Processing
SONAR provides a number of advanced audio processing commands for power users. Among
these are commands to remove silent sections of audio from the data and to apply fades, 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 clips, splitting long audio clips into a
greater number of shorter audio clips.
SONAR treats passages of absolute silence intelligently. It doesn’t store stretches of silence on disk,
and thereby conserves disk space. During a passage of absolute silence, SONAR sends no signal
to the digital output port; this results in cleaner audio playback. Remove Silence is great for
cleaning up your final audio mix, because it can mute all audio tracks in which the live performers
were “laying out.”
Using Remove Silence to split long audio clips into smaller ones opens a variety of creative
possibilities.
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 filter, 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.
