Intro to Surround Compressor in Final Cut Pro
Surround Compressor, based on Compressor, is specifically designed for compression of complete surround mixes. It is commonly inserted in a surround clip that carries 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.
Surround Compressor is divided into three sections:
The Link section at the top contains a series of menus where you assign each channel to a group.
The Main section includes controls common to all the main channels, and the threshold and output controls for each channel.
The LFE section on the lower right includes separate controls for the LFE channel.
