Bouncing Surround Audio Files
The surround settings display the file name extensions that will be appended to the file
names resulting from a surround bounce. Bouncing a surround mix will create more
audio channels than your usual stereophonic bounce/mixdown, and these extensions
are used to identify the files. Click on the various fields to edit the extensions.
Select Surround Bounce in the normal bounce dialog (after clicking the bounce button
at the bottom right of an Output Object or via File > Bounce). All outputs selected in the
surround settings will be bounced simultaneously, no matter which Output Object
bounce button is pressed.
Level
Audio Objects feature level meters that display the playback or input monitor level.
When you arm a track, in preparation for recording, the meter displays the input level.
The playback level is also displayed to the left of the track number in the Arrange
window, if View > Track Numbers/Level Meters is selected.
Peak Hold
As with conventional mixing desk meters, peak values are “held” on the display for a
few seconds, making them easier to read. The most recent maximum level is always
reliably displayed, even if your CPU power is insufficient for a smooth real time display
of levels.
