5. Click OK to remove silence from the selected data.
SONAR processes the audio as directed.
Removing DC Offset
Some models of audio hardware produce a DC offset while recording,
which is caused by electrical mismatches between the audio hardware and
the input device or instrument. Although imperceptible, DC offset may
cause problems in further stages of sound processing.
Note: An easy way to spot DC offset is to zoom in to a silent section of your
sound file. If the silent waveform matches the centerline in the waveform
display, your file does not contain DC offset.
Release Time (ms) The amount of time after the Close Level is
reached that the gate actually closes. This lets
the tail end of sounds pass through without
being clipped.
Look Ahead (ms) The value in this field causes the gate to open
slightly before the sound reaches the Open
Level so you don’t lose the sound’s attack.
