Apple Final Cut Pro 7 - Manual (Page 852)

How Audio Outputs Are Assigned Automatically
Final Cut Pro automatically configures audio output busses according to the selected
linked clip items in your sequence. This feature is often used with 5.1-channel surround
sound clips, but keep in mind that Final Cut Pro supports only the following 5.1-channel
surround sound format:
• Tracks 1 and 2: Left and right
• Track 3: Center
• Track 4: Low-frequency effects (LFE)
• Tracks 5 and 6: Left surround and right surround
Based on the clip items above, the Match Audio Outputs command would create the
following audio output bus groups: stereo 1 and 2 (left and right), mono 3 (center), mono
4 (LFE), and stereo 5 and 6 (left surround and right surround).
Here is how the sequence tracks would be assigned to the audio outputs:
• Tracks 1 and 2 (left and right): Stereo output 1 and 2
• Track 3 (center): Mono output 3
• Track 4 (LFE): Mono output 4
• Tracks 5 and 6 (left surround and right surround): Stereo output 5 and 6
Using the Match Audio Outputs Command
The Match Audio Outputs command automatically configures your audio outputs to
match the stereo and mono groupings of the selected audio clip in your sequence.
Note: In this case, the term audio clip refers to an audio clip item and all other audio clip
items linked to it.
To assign matching audio outputs to the selected audio clip in the Timeline
1 Select a single audio clip with linked audio clip items in the Timeline.
2 Choose Sequence > Match Audio Outputs, or press Option–Semicolon (;).
If the current audio outputs for the sequence do not match the configuration of the
selected audio items, Final Cut Pro warns you that your sequence outputs will be changed
to match.
Note: Final Cut Pro only supports even numbers of audio outputs. If the selected audio
clip spans an odd number of tracks (3, 5, 7, and so on), the Match Audio Outputs command
creates the next highest even number. For example, if the selected clip spans seven tracks,
eight audio outputs are created.
Your sequence audio outputs are reassigned so that the selected audio clip’s stereo items
are assigned to individual stereo output busses and the clip’s mono items are assigned
to individual mono output busses.
