Audio Performance
Exit other programs The more programs you have open, the
more CPU cycles you are taking away
from your project. Exit any programs
unnecessary to the task at hand.
Refrain from other activity during
playback
If you open and close windows or do lots
of editing while playback is in progress,
you may steal CPU cycles that would
otherwise be used for playback.
Apply some audio effects offline If you apply real-time effects that you are
satisfied with, consider using the Apply
Audio Effects button in the Console view
to apply those effects offline. Then
remove those effects from real-time use
and free up lots of CPU power.
Archive unused audio tracks Audio tracks that are muted continue to
place a load on your processor. To lessen
the burden and free up cycles to handle
more audio, archive all unused audio
tracks. See “Silencing Tracks” on page 3-
11 for more information.
Mix down your audio tracks If your project contains many different
audio tracks or many real-time effects,
you can use the
Mixdown Audio
command to reduce all of this content to
a stereo pair of tracks. Having done this,
you can archive the original tracks (in
case you need them later) and play only
the new tracks, lessening the
computational burden on your computer.
For more information, see “Mixing
Down and Distributing Audio” on page
9-27.
Change File I/O Buffer Size in the
Options-Audio-Advanced dialog box
Most hard disks work best with the
default setting of 64 KB. Yours may work
better with 128, 32, or 16. If those
values don’t help, try 256, 512, or move
on to another remedy.
Defragment your hard disk If your hard disk is fragmented, playback
of audio will be slower. Use the Disk
Defragmenter to correct the situation.
Turn off the Clip Audio Mix Upon
Overflow option in the Options-
Audio-Advanced dialog box.
Unless your mix is really distorted, you
won’t usually need this option.
