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 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 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. Record input monitoring is only available in the
full version of Vegas software.
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 dialog.
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 software while you are
recording.
