 General
 Apply Digital Deemphasis checkbox: Specifies whether input audio data is
pre-emphasized and needs to be de-emphasized before encoding.
 LFE Channel
 Low-Pass Filter checkbox: Select this option to apply a 120 Hz low-pass filter to the
Low Frequency Effects (LFE) channel. Turn off this filter if the digital signal fed to
the LFE’s input does not contain information above 120 Hz.
 Full Bandwidth Channels
 Low-Pass Filter checkbox: Select this option to turn on a low-pass filter with a cutoff
near the available audio bandwidth that is applied to the main input channels. If
the digital signal fed to the main input channels does not contain information
above the available audio bandwidth, you can turn off this filter. Compressor
automatically determines the available bandwidth.
 DC Filter checkbox: Select this option to turn on a DC high-pass filter for all input
channels as a simple way to remove DC offsets. Most mixed audio material is
already free of DC offsets.
 Surround Channels
 90° Phase-Shift checkbox: Select this option to generate multichannel AC-3 streams
that can be downmixed in an external 2-channel decoder to create true Dolby
Surround–compatible output.
 3 dB Attenuation checkbox: Select this option to apply a 3 dB cut to the surround
channels of a multichannel film soundtrack being transferred to a consumer home
theater format. Cinema surround channels are mixed 3 dB “hot” (higher) relative to
the front channels to account for cinema amplifier gains.

Exporting a Master Mix Using Compressor
The Export dialog in Soundtrack Pro offers a direct link to the Compressor application.
Compressor is the high-speed video and audio encoding tool for Final Cut Studio. It
provides an efficient way to transcode between professional formats, or to convert
content so that it can be experienced on many different platforms and devices
(including websites, Apple TV, an iPod, CD-ROM discs, DVDs, cell phones, and so on).
When you export using Compressor, you can use custom presets that you create in
Compressor or the presets included with Compressor.
