New Ducker Plug-in
The Logic Pro 7.2 Update features the new Ducker plug-in (in the Logic > Dynamic
submenu).
Important: For technical reasons, the Ducker plug-in can only be inserted in Output
and Bus Objects.
Ducking is a common technique used in radio and television broadcasting: when the
DJ/announcer speaks while music is playing, the music level is automatically reduced.
When the announcement has finished, the music is automatically raised to its original
volume level.
The Ducker plug-in provides a simple means of performing this process. It can even
reduce the music level before the speaker starts (but this introduces a small amount of
latency).
To use the Ducker plug-in:
1 Insert the Ducker plug-in into an Audio Output or Bus Object.
2 Assign all track outputs that are supposed to duck (dynamically lower the volume of
the mix) to a bus.
3 Select the buss that carries the ducking (vocal) signal in the Side Chain menu of the
Ducker plug-in.
Note: Unlike all other side chain capable plug-ins, the Ducker side chain is mixed with
the output signal after passing through the plug-in. This ensures that the ducking side
chain signal (the voice over) is heard at the output.
4 Adjust the Duckers parameters.
The Ducker plug-in offers the following parameters:
 Intensity: Defines the amount of volume reduction (of the music mix track—this, in
effect, is the output signal).
