Surround Compressor in Logic Pro for Mac

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.

To add Surround Compressor to your project, choose Dynamics > Surround Compressor in a channel strip Audio Effect plug-in menu. See Add, remove, move, and copy plug-ins in Logic Pro for Mac.

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.

The interface is divided into three sections:

• The Link section at the top contains menus used to assign each channel to a group. See Surround Compressor Link parameters.

• The Main section includes controls common to all the main channels and the threshold and output controls for each channel. See Surround Compressor Main parameters.

• The LFE section on the lower right includes separate controls for the LFE channel. See Surround Compressor LFE parameters.
