Mixing Latency
Pro Audio has a slider in the DirectShow Audio dialog box, on the
General tab, to set mixing latency. Mixing latency is the amount of time
Pro Audio allocates to prepare a buffer full of audio data for playback.
Turn off the Apply Dither option in
the Options-Audio-Advanced dialog
box.
Dithering subtly improves your mix, but
most people can’t hear it. Turn it back on
for mastering.
Enable disk caching By default, Pro Audio bypasses all disk
caching, which typically results in better
performance with audio data. If your
computer has a very large amount of
RAM (128 MB or more) and your audio
tracks include many repeated sections,
enabling caching may improve Pro
Audio’s audio performance. Choose
Options-Audio
and click the Advanced
tab to change the disk cache settings.
Record audio at a lower sampling
rate
If you don’t require CD quality 44.1 kHz
audio, then record your audio at a lower
sampling rate of 22.05 kHz or 11.025
kHz. Choose
Options-Audio
to change
the sampling rate. This method is useful
only before you start work on a project.
Once the audio sampling rate for a project
has been set, it cannot be changed.
Disable the Display Clip Contents
options
Drawing the contents of audio clips in the
Clips pane uses some CPU cycles. If you
are using a slow machine, you may want
to disable this feature. To do so, right-
click in the Clips pane, choose
View
Options
, and disable the Display Clip
Contents option.
Turn off the option to draw audio as
it plays
The DrawPlayingAudio setting in the
initialization file, if enabled, causes
audio waveforms to be drawn as the
track or audio scrolls during playback.
Disable this option to conserve CPU
cycles. To do so, make sure that
[DrawPlayingAudio=0] appears in the
cakewalk.ini
file. For more information on
initialization files, see
Appendix E:
Initialization Files
