Adobe AUDITION 1.5 - Manual (Page 230)

CHAPTER 10 222
Creating Surround Sound
Play All Plays from the cursor location, playing the multichannel mix with all tracks that
are checked in the Track List. Like Play Track, Playback always plays to the end of the
session, regardless of the current zoom level.
Time indicator Located next to Play All, this indicator shows the time in the preview
playback.
Preview Volume Controls the volume of the preview playback, without affecting the
volume of the exported files. That is, it doesn’t change the amplitude of the exported WAV
or encoded WMA files that are created from the Multichannel Encoder, nor does it affect
the levels measured by the 6-channel Output Meter. Use the Master Level slider for
changing these.
Output meters (FL, FR, C, LFE, Ls, Rs) This set of six meters displays the output of each
channel during preview. During Play Track, the meters display the output of only the
selected track. During Play All, the meters display the output of the complete 5.1 mix.
These levels are what the actual levels will be for your exported WAV or WMA files from
the session. You can attenuate the overall 6-channel level by using the Master Level slider
beneath the meters.
Master Level Sets the audible level of your preview playback. However, it is primarily
intended to adjust the amplitude of the exported or encoded files. Use this slider and
reference the meters to optimize the overall peak amplitude of the 5.1 channel mix so that
none of the channels are clipping.
Preview Device, Format Displays the currently selected device to which Adobe Audition
routes its 6-channel output. (See “Setting the preview device and format” on page 222.)
Setting the preview device and format
The Preview Device, Format option lets you specify the device and format of the
previewed audio. This option also displays the currently selected bit rate for preview
playback. For information about device requirements, see “Using the Multichannel
Encoder” on page 214.
To make changes to the device and bit selections:
1 Click the Change button to the right of the Preview Device, Format option.
2 From the Multichannel Output Device menu, specify the preview sound card.
