Apple Final Cut Pro 6 - Manual (Page 299)

298 Part IV Logging, Capturing, and Importing
 Audio capture checkbox: Select this option to enable audio capture for the current clip.
 Input Channels: When an audio interface is connected to your computer and selected
in your current capture preset, Final Cut Pro automatically detects the number of input
audio channels available. In this case, the pop-up menu is grayed out.
If no audio device is connected, you can choose how many audio inputs you
eventually want to capture from (once an audio interface is connected). This is
helpful when you are logging tapes without an audio device connected. Don’t select
more audio inputs than you will have available when you capture.
Note: If your audio interface is disconnected, and you log clips with more audio
input channels than your audio interface has, Final Cut Pro restricts the number of
audio channels that are captured to the number of available input channels on the
interface. For example, if you log clips with eight audio input channels, and then
batch capture those clips using an audio interface that only supports four input
channels, only four channels are captured.
 Preview: Select this option to listen to the incoming signal on the audio output
selected in the Sound pane of System Preferences. Each audio channel you enable
for capture is routed to a corresponding output on your audio interface, while
disabled channels are not heard. If your audio interface has less audio outputs than
the number of channels you are capturing, the audio is downmixed to two channels
(mono channels are panned to the center and stereo pairs are previewed in stereo).
This does not affect your captured media files; only the preview of audio during
logging and capturing is affected.
 Master Gain: This slider allows you to adjust the gain on all audio channels
simultaneously. You can also enter a gain or attenuation value in decibels in the
corresponding field.
Note: Not all devices support a master gain control from Final Cut Pro.
 Individual channel meter: Each audio channel meter shows the current level of the
audio entering your audio interface.
Note: If the Preview option is enabled, and an audio channel is disabled for capture,
then the audio meter does not display levels.
 Clipping indicator: Each audio channel meter has a clipping indicator that lights up
when audio levels above 0 dBFS are encountered. This indicator stays lit until you
stop and start playback again.
 Stereo/Mono control: Enabling this control tells Final Cut Pro to capture the two
corresponding audio channels as a stereo pair. When this control is disabled, you can
select one or both audio channels for capture. In this case, each channel is captured
and handled as a discrete mono channel.
 Capture Audio Channel control: Enabling this control tells Final Cut Pro to capture the
corresponding audio channel.
