Audio processing and functions
Attack Time
The time it takes for the gate to open fully after the audio
level has exceeded the threshold level.
Min. Opening Time
This is the shortest time the gate will remain open. If you
find that the gate opens and closes too often when pro
-
cessing material that varies rapidly in level, try raising this
value.
Release Time
The time it takes for the gate to close fully after the audio
level has dropped below the threshold level.
Linked Channels
This is available for stereo audio only. When it is activated,
the Noise Gate is opened for both channels as soon as
one or both channels exceed the Threshold level. When
Linked Channels is deactivated, the Noise Gate works in
-
dependently for the left and right channel.
Dry/Wet mix
Allows you to specify a mix ratio between “dry” and pro-
cessed sound.
Pre-Crossfade and Post-Crossfade
See “Pre/Post-Crossfade” on page 246.
Normalize
The Normalize function allows you to specify the desired
maximum level of the audio. It then analyzes the selected
audio and finds the current maximum level. Finally it sub
-
tracts the current maximum level from the specified level
and raises the gain of the audio by the resulting amount (if
the specified maximum level is lower than the current max
-
imum, the gain will be lowered instead). A common use for
Normalizing is to raise the level of audio that was recorded
at too low an input level. The dialog contains the following
settings:
Maximum
The desired maximum level for the audio, between -50 and
0 dB. The setting is also indicated below the Gain display
as a percentage.
Pre-Crossfade and Post-Crossfade
See “Pre/Post-Crossfade” on page 246.
Phase Reverse
Reverses the phase of the selected audio, turning the
waveform “upside down”.
The dialog contains the following settings:
Phase Reverse on
When processing stereo audio, this pop-up menu allows
you to specify which channel(s) are phase-reversed.
Pre-Crossfade and Post-Crossfade
