Clip adjustments and track adjustments are combined for final output. So if you reduce a
clip’s audio level by −3 dB and reduce the track audio level by −3 dB, you’ll have a total
drop of −6 dB.You can apply clip-based audio effects and modify their settings in the Effect Controls
panel, but track-based audio adjustments can be modified only in the Audio Track Mixer or
directly on the timeline.Clip-based audio adjustments and effects are applied before track-based adjustments and effects.
The order in which adjustments are applied can have a big impact on results, especially when
working with effects.
Defining master track output
Sequences have settings that closely match the way a media file would be defined. These
settings include a frame rate, frame size, and pixel aspect ratio, for example.
The audio mastering setting defines the number of audio channels the sequence outputs. This is a
little like configuring the audio channels for a media file. In fact, if you export the sequence
using the option to match sequence settings, the sequence audio mastering configuration will be
the audio format for the new file.
When you create a new sequence, the audio mastering setting is in the Tracks tab of the New
Sequence dialog box, under Audio.
