Ducker Parameters
The Ducker has the following parameters:
• Ducking On and Off buttons: Enable or disable ducking.
• Lookahead On and Off buttons: Enable to ensure that the Ducker reads the incoming
signal before processing. This results in no latency—it is primarily intended for slower
computers.
• Amount slider and field: Defines the amount of volume reduction of the music mix
channel strip, which is, in effect, the output signal.
• Threshold slider and field: Determines the lowest level that a side-chain signal must
attain before it begins to reduce the music mix output level—by the amount set with
the Intensity slider. If the side-chain signal level doesn’t reach the threshold, the music
mix channel strip volume is not affected.
• Attack slider and field: Controls how quickly the volume is reduced. If you want the
music mix signal to be gently faded out, set this slider to a high value.
This value also controls whether or not the signal level is reduced before the threshold
is reached. The earlier this occurs, the more latency is introduced.
Note: This only works if the ducking signal is not live—the ducking signal must be an
existing recording. The host application needs to analyze the signal level before it is
played back in order to predefine the point where ducking begins.
