Wave Profiler (MME and WDM drivers only)
Wave Profiler attempts to detect the make and model of your sound card,
which determine the card’s DMA (Direct Memory Access) settings. Once
Wave Profiler identifies the card, it displays the results and asks whether
you want to use the default settings for that card or to override them:
If Wave Profiler has identified your card correctly, you may accept the
default settings. Otherwise, Wave Profiler will run a series of tests to
attempt to determine the correct DMA settings. Usually this process is
successful; however, if it is not, you will need to enter the correct settings in
the Device Profiles tab of the Audio Options dialog box.
To determine the correct settings, consult your sound card documentation.
Our web site, at www.cakewalk.com, contains the latest DMA settings for
commonly used sound cards.
The Wave Profiler utility runs automatically the first time you run SONAR.
You need not run it again unless you install a new sound card or an updated
driver for your current sound card.
Wave Profiler will not analyze the card at the 48 kHz sampling rate. It
assumes that 48 kHz settings are the same as 44 kHz settings. If your
sound card doesn’t sync to 48kHz, you may need to enter the settings
manually.
ASIO Panel (ASIO drivers only)
This button opens a dialog where you can set the buffer size for your ASIO
driver and change the driver configuration. See your sound card’s
documentation for more information.

• Enable Read Caching and Enable Write Caching—Choosing either of
these options lets SONAR use the Windows disk cache while reading
or writing audio data. SONAR will usually perform best with all caching
disabled, which is the default setting. If your computer has an older IDE
