Audio Project Settings
You can save multiple Audio Project settings and select one as the active setting. If you edit an
inactive setting, your Avid editing application does not display items that are not saved. For
example, Mix Mode does not display in an inactive setting because you cannot save it in the
Project settings.
n
The Direct Out mode is saved in the Audio settings, not the Audio Project settings. You set it in
the Output tab of the Audio Project window but the system saves the value in the active Audio
settings.

Tool Buffer Size in
Samples (Software-only
Models)
Defines the size of the host audio play buffer during audio loop play and audio tools
play (such as volume automation recording). Reducing the tools play buffer size
decreases the overall latency between the time you adjust an audio parameter in your
Avid editing application and the time you hear those changes through the speaker.
n
Changing this option might cause audio or video underruns, dropped frames,
or increased noise in the audio output. Because performance varies from
machine to machine, experiment to find a value that works best. For best results
when adjusting this option, turn off or disconnect all DV devices.
For more information, see “Adjusting the Play Buffer Size for Audio (Software-only
Models)” on page 787.
To return this option to its default value, click the rs (recommended sample) button.
Monitors Volume Controls the volume of the desktop speakers. Use the Mute button to mute audio
output to speakers or headphones.
