Improving audio performance
System configuration
System configuration
This section covers optimizing your system configuration to work with SONAR.
See:
“Enabling and disabling audio devices”
“Bit depths and float resolution”
The Wave Profiler
The Wave Profiler is a utility that analyzes the sound cards in your computer and determines the
best DMA (Direct Memory Access) settings for communicating with SONAR. These DMA settings
are displayed in samples, at the sample rates and bit depths your sound card supports. The Wave
Profiler also sets a value in milliseconds for the Buffer Slider, which controls mixing latency. The
Wave Profiler is unnecessary if you are using an ASIO driver.
The DMA settings are used to ensure that a project that contains both MIDI and digital audio plays
back in tight synchronization. If SONAR is not configured properly with your audio device’s DMA
settings, MIDI and digital audio material may not play back correctly.
Note
to users of previous Cakewalk products
: The DMA settings in versions of Cakewalk prior to
SONAR 1.0 were displayed in bytes rather than samples. Using your previous DMA settings in
SONAR will not work. Try the settings that wave profiler displays, and if you are not satisfied, only
then attempt to optimize your settings.
The Wave Profiler utility runs automatically the first time you run SONAR. The wave profiler
determines the best DMA settings for the supported bit depths and sample rates of your sound card.
All of your audio settings are listed in the
Preferences
dialog box, which you open with the
Edit >
Preferences
command. The following list summarizes all the settings that the Wave Profiler sets.
You can override all of them except what audio drivers are listed in the Drivers tab:
• Input and output drivers
• DMA buffer sizes (in samples)
• Mixing latency
If you experience MIDI and audio synchronization problems during playback, before contacting
technical support, run the Wave Profiler and try the default settings.
Note:
It is possible to load a 48 kHz project when you are using a sound card that does not
support 48 kHz. SONAR does not warn you when you do this. Your project may crash, or it may
appear to record audio when your project is not actually recording.
