Improving performance with digital audio
default setting is 2. For more information, see “Mixing latency” on page 1192, and “Dropouts and
other audio problems” on page 1197.
CPU meter/Disk meter/Dropout indicator
SONAR has several tools to help you identify and correct audio problems, including the CPU meter
and Disk meter in the Control Bar’s Performance module, and the Dropout indicator in the Transport
module.
Figure 343. The Transport module.
The Dropout Indicator appears whenever your project requires more resources than your CPU,
main memory, and disk can supply. For details, see “Dropouts and other audio problems” on page
1197.

The Performance module contains the following controls:
• CPU meters. Displays the time it takes to process a buffer full of audio data as a percentage of
the maximum time available to process that data and maintain uninterrupted playback. There is
one CPU meter for each core in your computer, up to 32 cores. There is some tolerance built into
the meter, so it is possible that it will exceed 100% at times (more so during recording than
playback).
Note: The width of the Performance module depends on the number of CPU cores available.
