Improving Audio Performance
discontiguous locations on your disk. Accessing these discontiguous
chunks can consume extra processing time, which can lead to dropouts.
Try defragmenting your project file:
1. Open the project file that has audio problems.
2. Save it as a Cakewalk Bundle (.
CWB) file by selecting Save As from the
File menu and selecting Cakewalk Bundle from the Save As Type drop
down list and clicking the save button.
3. Close the project.
4. Open the Cakewalk Bundle you just closed
Saving then re-opening the bundle file automatically defragments the audio
data used by the project, reducing the chances of a dropout or other audio
problem.
When you are ready to save the file again, you may want to save it as a
normal (.
CWP) file. Saving and opening .CWP files takes less time than
saving and opening bundle files.
Your sound card's driver may be obsolete
Obtain and install a new sound card driver (if available):
• Consult your sound card manufacturer's web site (or contact their
Customer Service department) to check for the availability of a later
driver version. If one exists, obtain it and install it on your computer
according to their instructions. With the new driver installed, restart the
computer, then delete the file cw9auddx.ini from your SONAR folder.
Launch SONAR and let it re-profile your audio hardware. When it's
done, re-test your audio recording/playback.
• If problem(s) persist, continue with the next step.
There may be a conflict with your video card or other
multimedia streaming card
Some video drivers contain bugs which can interfere with SONAR's
operation. Or, the driver may be "stealing" excessive CPU time away from
SONAR (some video card vendors, in an attempt to make their cards
operate faster, supply drivers that tie up the computer's bus for relatively
long intervals (so-called “PCI bus contention”). This can interrupt the
smooth flow of audio data between SONAR and the sound card's driver.)
Try to remove the video card conflict as follows:
• Try turning off "hardware acceleration" on your video card (if available).
This may cause more sluggish screen drawing, but may improve the
