Reference
audio program must start recording or playback on each of them, one at a time. If
left uncorrected, this would cause small offsets between the stereo pairs.
The Synchronization settings solve this by creating a group of synchronized input
and output pairs. The OASYS PCI will not start either recording or playback until
all of the devices in the group have received the start command from the digital
audio program.
Auto Sync
When Auto Sync is enabled, synchronization happens automatically. Whenever
you select or de-select a OASYS PCI input or output pair in your digital audio
program, Auto Sync will add or delete the pair from the synchronization group.
This should work well for most applications; however, you can also disable Auto
Sync, and makes settings manually using the Custom Synchronization window
(under the Custom button).
Custom...
Pressing this button brings up the Custom Synchronization window, which allows
you to manually control the OASYS PCI's wave device synchronization. For more
information, see "Custom Synchronization," on page 134.
When Auto Sync is checked, the Custom button is disabled, and any settings
previously made in the Custom Synchronization window will be ignored.
Volume/Balance Control
Each stereo I/O pair has a Control Enable button, which allows you to enable and
disable volume and balance control for that stereo pair. These buttons allow you to
enable or disable all of these buttons at once.
For more info on the Control Enable buttons, see "Control Enable" on page 132,
below.
Unless you have a specific need for volume and balance control in this window, we
recommend that you disable all Control Enable buttons. This will save CPU
processing power; for more information, see "When to use volume/balance
control" on page 132.
Enable All
Pressing this button turns on all of the Control Enable buttons at once.
Disable All
Pressing this button turns off all of the Control Enable buttons at once.
Volume slider
Each stereo output pair has a volume slider, which controls the overall output level
for the wave device. To adjust the left and right channels independently, use the
balance slider in conjunction with the volume slider.
