Dropouts Happen in High Bit-depth or
High Sample Rate Audio
If you are hearing consistent dropouts/clicks in your audio and if your
project contains high bit depth (32/64 bit) or high sample rate audio (88.2K
or higher), it may be indicative of a too small I/O buffer size. If so try a
higher I/O buffer size like 256 or 512. If audio problems persist, reset to 128
and try a different remedy.
Use the Options-Audio command to open the Audio Options dialog, click
the Advanced tab, and in the I/O Buffer Size (KB) field, enter 256 or 512.
Patching an Effect into SONAR Causes
a Dropout
You may have simply reached the maximum number of tracks and effects
your CPU can handle. However, if your CPU meter doesn’t appear to be
maxed out, or other plug-ins seem to work, you may need to address the
problem by editing a line in the AUD.INI file.
Using Notepad, open the AUD.INI located in the directory where you
installed SONAR. The default value of the ExtraStreamBufs variable is 0.
Try changing that value to 1, saving AUD.INI and patching in the effect that
caused the dropout. If it still causes a dropout, try changing the value in
ExtraStreamBufs to 2. Continue to double the value in this variable until you
reach 32 (4, 8, 16, 32). If a value of 32 does not fix the problem, it is time to
try something else. See Dropouts and Other Audio Problems for more
information about potential reasons for dropouts.
