Improving audio performance
Improving performance with digital audio
Some drivers change the reported sample position based on how long a buffer switch took to
complete and this can cause problems since SONAR expects the reported position to be in sync
with the number of buffers actually streamed.
This
Aud.ini
variable defaults to 0.
Minimize driver state changes
SONAR has an option to not reset audio devices each time playback or recording starts. This option
minimizes device state transitions in response to transport operations. When enabled, SONAR
attempts to keep the device in a running state as far as possible.
To configure the MinimizeDriverStateChanges option
1.
Go to
Edit > Preferences > Audio - Configuration File
.
2.
Under
Configuration Settings
, click
Edit Config File
.
The
Aud.ini
file opens in the default Windows text editor.
3.
In
Aud.ini
, locate the entry called
MinimizeDriverStateChanges
and set it to the desired
value. For example:
MinimizeDriverStateChanges=1
Valid values are as follows:
• 0 = off.
• 1 = On for ASIO only (default).
• 2 = On for WDM only.
• 3 = On for both ASIO and WDM.
4.
Save
Aud.ini
and close the Windows text editor.
5.
Click
Reload Config Settings
to reload the current audio configuration settings from
Aud.ini
.
Queue buffers
SONAR allows you to set the number of queue buffers in
Edit > Preferences > Audio - Driver
Settings
. A higher number of queue buffers will take longer to fill, and therefore cause an increase
in latency. A lower number of queue buffers decreases latency, but may cause “dropouts.” The
default setting is 2. For more information, see
on page 1305, and
Note:
The
MinimizeDriverStateChanges
variable only applies when using ASIO or WDM
driver modes, not when using the MME driver mode.
