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 checkbox 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 checkbox is selected, buffers will not be created prior to starting playback. Some devices do not behave properly if this checkbox 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 MME from 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 checkbox if you want to be able to perform record input monitoring using a wave driver. When the checkbox is cleared, record input monitoring is not available. This setting has no effect on standard audio playback.

ASIO

When an ASIO driver is selected, the Advanced Audio Configuration dialog displays information about the settings for the selected driver. Click the Configure button to open the driver manufacturer's configuration applet and adjust settings.

The lower portion of the dialog lists the device name and the name for each of the selected ASIO device's ports. You can use these controls to customize input and output port names. For more information, see Customizing ASIO port naming
