PART 3: The Acadia Audio System
Increasing either the File Buffers or the
File Buffer Size is likely to increase the
number of simultaneous audio tracks you
can play, as well as the number of
plug-ins, sends, and EQ bands you can
use. As a result, however, you may notice
that it takes longer to start and stop playing
digital audio. This is because your
Macintosh needs to fill the buffer with
digital audio from your hard disk.
The amount of RAM required for the file
buffers is determined by the File Buffer
Size, File Buffers, and the number of
specified Audio Instruments.
AUDIO PREFERENCES
Use the Audio Preferences dialog to set
various record and playback options for
the Acadia audio system. To open the
Audio Preferences dialog, choose
Audio>Audio Preferences.
Process Ahead
When Process Ahead is checked, general
processing of audio for Vision is
more efficient, thereby allowing you to
use more audio tracks, sends, plug-ins
and EQ bands without encountering performance
errors.
However, when Process Ahead is
checked, Vision is less efficient in other
ways. The latency for “thruing” of audio is
more evident; using mute, solo, and
faders in Console Windows is less responsive;
and initial playback of audio takes a
little longer after clicking the Play button.
For general recording and editing, you
will probably want to disable Process
Ahead. However, when you are ready to
do your final mix down, you should
enable Process Ahead.
