Advanced audio preferences
You can access advanced settings by clicking the Advanced button on the Audio Device tab. The Advanced Audio Configuration
dialog displays all of the audio devices that are installed on your computer and allows you to set the controls for each device.
Adjusting the playback buffering slider
The playback buffer controls how much memory is used when playing back your project. This preference is useful, but must be
carefully adjusted. If you set the buffer size too high, you may experience gapping during playback. Conversely, if you set the buffer
size too low, you may experience gapping as well because Vegas Pro software has too little memory to work with during playback.
The playback buffer slider should be set to balance RAM usage and playback buffering. The rule is to set this slider as low as possible
without introducing gapping.
Enable track buffering Select this check box and drag the Track buffering slider if you want to adjust the
amount of audio that is prerendered ahead of the cursor position.
When the check box is selected, a separate processing thread is used to render audio
from tracks. On multiprocessor or multicore computers, a thread will be created for
each logical processor.
When the check box is cleared, a single processing thread is used to render audio from
tracks and busses.

Preference Description
Audio devices This list contains all of the audio devices that are installed in your computer. Selecting
one from the list allows you to set the options below for that device.
Interpolate position During project playback, you may notice that the cursor position is different than
what you are hearing. This problem stems from inaccuracies in some audio devices.
Select this control’s check box to have Vegas Pro software attempt to compensate for
the inaccuracies by interpolating the cursor’s correct position during playback or
recording.
Position bias The position bias control gives you additional cursor control when it is inaccurately
displayed during project playback and recording. If you have enabled the Interpolate
position control and are still experiencing cursor position inaccuracies, move the
Position bias control forward or backward to compensate for the inaccuracies of the
audio device.
Do not pre-roll buffers before
starting playback
When this option is not selected, Vegas Pro software begins storing (buffering) project
audio information prior to playback. This storing is very fast and unnoticeable in most
cases. However, some audio devices stutter when you begin playback as a result of the
buffering process. If your audio stutters when you start playback, select this check box
to prevent buffering audio information prior to playback.
Audio buffers Drag the slider to set the number of audio buffers that will be used. Adjusting this
setting can help you synchronize the input and output for record input monitoring.
Buffer size (samples) Choose a setting from the drop-down list to indicate the buffer size you want to use.
Choose MME to use the Playback buffering setting on the Audio Device tab in the
Preferences window.
Priority Choose a setting from the drop-down list to set the priority that is assigned to your
audio buffers. Increasing the buffers’ priority can help you attain smoother playback,
but it can also adversely affect other processes.
Enable input monitoring Select this check box to enable the monitoring of your recording input through Vegas
Pro software while you are recording.
