1306 Initialization files
Initialization file format
ShowMultiChannelInputs =
<0 or 1>
Boolean 1 This is a line in the Wave section of the Aud.ini file
that specifies whether SONAR uses multichannel audio
devices as multiple stereo pairs or just a single stereo
pair.
ShowMultiChannelOutputs=
<0 or 1>
Boolean 1 This is a line in the Wave section of the Aud.ini file
that specifies whether SONAR uses multichannel audio
devices as multiple stereo pairs or just a single stereo
pair.
MinimizeDriverStateChanges
=<0 or 1>
Boolean 1
This is a line in the Wave section of the
Aud.ini file
that controls whether or not audio devices are reset in
response to transport changes (play/stop).
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.
MMCSSTaskKey=
<task name>
Name Pro Audio By default, SONAR uses the MMCSS task profile
named Pro Audio. If desired, you can instruct SONAR
to use a custom MMCSS task profile.
ManageASIOThreadPriority=
<0 or 1>
Integer 1 This determines whether SONAR manages the ASIO
thread priority when necessary. This defaults to 1.
EnableCacheWriteThru=
<0 or 1>
Boolean 1 This variable enables disk write thru caching. When
write thru caching is on, data recorded to wave files is
written to the hard disk immediately, circumventing the
hardware disk cache. Having write thru caching off can
be more efficient for disk I/O but can result in data loss if
your system crashes.
RealtimePreroll=<0 or 1> Boolean 0 This variable specifies whether preroll buffers are
pumped as fast as possible or in real-time.
Prerolling in realtime may improve buffering and CPU
load when using hardware DSP solutions such as the
Universal Audio UAD-1 or Focusrite Liquid Mix.
WaveInBuffers=<2 - 8> Integer 8 When using the External Insert plug-in alongside the
original dry signal in WDM mode, you might notice a
flanging or flamming effect. To minimize this effect, we
recommend that you set the WaveInBuffers
Aud.ini variable to 2.
Note: Setting the value to 2 might have an adverse
effect with certain audio hardware, causing recording to
drop out. If this occurs, reset the value to 8 and try using
ASIO drivers if your hardware has ASIO support.
