<strong>Buffering</strong> settings determine how many seconds of audio
|
|
off of disk will be buffered in memory. Longer settings reduce the risk
|

of buffer under-runs but consume more memory. The default value is

5.0 seconds.

<strong>Denormals</strong> are a specific type of very small numbers that
|
|
can cause issues with CPU consumption when using some plugins in some
|
|
circumstances.
|
|
</p>
|
|
<p>
|
|
Ardour provides two methods of handling the issue. Try different
|
|
combinations of these settings to to find the setting that minimizes CPU
|
|
consumption.

<strong>Processor handling</strong>, if the computer's hardware

supports it, offers two methods that can be used individually or

combined. Flush to zero and denormals are zero.
