Use Noise Gate in Ducking mode
1. In Logic Pro, insert Noise Gate into an aux channel strip and click the Ducker button.
2. Assign all channel strip outputs that you want to “duck” (dynamically lower the volume
of the mix) to a bus—the aux channel strip chosen in step 1.
3. In the Noise Gate plug-in window header, choose the bus that carries the ducking
(vocal) signal from the Side Chain pop-up menu.
Note: The ducked side chain is mixed with the output signal after passing through the
plug-in. This ensures that the ducking side chain signal—the voiceover—is heard at
the output.
4. Adjust Noise Gate parameters as required.
Surround Compressor
Logic Pro Surround Compressor overview
Surround Compressor, based on the Compressor plug-in, is specifically designed for
compression of complete surround mixes. It is commonly inserted in a surround output
channel strip or in audio or aux channel strips—busses—that carry multichannel audio.
You can adjust the compression ratio, knee, attack, and release for the main, side,
surround, and LFE channels, depending on the chosen surround format. All channels
include an integrated limiter and provide independent threshold and output level controls.
You can link channels by assigning them to one of three groups. When you adjust the
threshold or output parameter of any grouped channel, the parameter adjustment is
mirrored by all channels assigned to the group.
