Item Description
Audio devices This list contains all of the audio devices that are installed in your
computer. Select a device from the list to set the options below for
that device.
Interpolate position When check box is selected, the application will attempt to
compensate for inaccurate devices by interpolating the playback or
recording position. If you notice that your playback cursor is offset
from what you are hearing, enable this option for the playback
device.
Position bias If the position of playback or record does not match what you hear
after you enable Interpolate position, you can attempt to
compensate using the Position bias slider.
Moving this slider will offset the position forward or backward to
compensate for the inaccuracies of the device.
Do not pre-roll buffers
before starting
playback
When this check box is selected, buffers will not be created prior to
starting playback. Some devices do not behave properly if this check
box is cleared.
If your audio stutters when you start playback try checking this
option.
Audio buffers Drag the slider to set the number of audio buffers that will be used.
Adjusting this setting can decrease gapping or help you synchronize
the input and output for record input monitoring.
Buffer size 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.
For example, if you choose MMEfrom the Buffer size drop-down, set
the Audio buffers slider to 5, and set Playback buffering to 0.35
seconds, five 0.07-second buffers will be created.
If you choose 1024 from the Buffer size drop-down and set the
Audio buffers slider to 5, five 1024-byte buffers will be created.
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 if you want to be able to perform record input
monitoring using a wave driver. When the check box is cleared,
record input monitoring is not available. This setting has no effect on
standard audio playback.
