INSTALLATION
Applying OPTIMOD-PC's Output to WAVE Devices
vice. Therefore, to use WMP as a playout application, you must set
OPTIMOD-PC as the Default Sound Device in Windows.
The OPTIMOD-PC DirectSound Driver allows digital audio playout applications to
output multiple sources simultaneously to one sound device. This eliminates the
need for multiple sound cards or sound cards with multiple sound devices for each
player and allows multiple players to mix automatically in automated operation,
independent of sample-rate and/or bit-rate. If individual outputs for each player are
not needed, this feature of DirectSound eliminates the need to mix all player out-
puts together externally,
Please note that some applications (like RealPlayer, as of this writing)
have volume controls that affect the Windows master volume instead of
just their own output levels. See About the Interaction between
OPTIMOD-PC's Input Mixers and Your PC's Built-In Mixer on page 2-25.
Note also that if the sample rate of the source material is different from
48 kHz (OPTIMOD-PC's native sample rate), the operating system will ap-
ply the appropriate sample rate conversion.
OPTIMOD-PC's WAVE output
looks like the output of a
sound card to the host com-
puter. Any application that
can receive the output of a
standard Windows WAVE de-
vice can use this output. Most
such applications have a menu
item that lets you select the
particular WAVE device from
which they are receiving in-
put;
select
"OPTIMOD-PC."
Once you have done this, you
can set the drive level to the
application
via
the
output
attenuator
OPTIMOD-PC I/O Mixer. You
can select the source that drives the application (PC WAVE output, output of Direct
Mixer, output of OPTIMOD-PC pre-limiter, or output of OPTIMOD-PC post-limiter)
via the drop-down selector located above this attenuator.
For example, the figure shows Adobe Audition 2.0 Audio Hardware Setup.
If you have more than one OPTIMOD-PC card installed, these will be known to Win-
dows as "Orban Optimod 1101 (serial number of card #1)," "Orban Optimod 1101
(serial number of card #2))," etc.
This is mainly relevant to users running multiple instances of a streaming
encoder program like Orban Opticodec-PC, Real/Helix Producer or Win-
dows Media Encoder. Typically, each instance of the streaming program
is connected to a separately named OPTIMOD-PC WAVE device. For ex-
ample, if you were running two streams, one instance of HELIX Producer
WAVE
