Wadia USB Audio Driver Operation
Control Panel Settings
The 321 USB Control Panel allows changes to be
made from the default settings. These include Latency,
Sample Rate and Audio Stream Input Output (ASIO)
Control. Refer to figure 18.
Note: It is not necessary for the Wadia USB Control
Panel to be running, unless it is desired to make
changes to the default settings.
LAT E NC Y:
The default Latency Setting is chosen for contempo-
rary computers and their performance capabilities.
When the Wadia USB Audio Driver is installed on
a legacy computer with slower processing speed, it
may occasionally produce clicks/pops in the music. To
resolve this if it occurs, increase the Latency Setting
(increase buffer size).
SAMPLE RATE:
The Sample Rate pull down Window indicates the
Sample Rate choices of the connected Wadia USB
Digital Audio Product. It also communicates the se-
lected choice of Sampling Rate to the active Windows
Playback Program.
Note: In general, when the original music is recorded
at a higher Sampling Rate, the result is usually
more detail in the music. However, this higher
rate results in consuming larger amounts of stor-
age space. The Sample Rate usually should be set
to match the Sample Rate of the music recording
being played back.
ASIO HOSTS CAN CHANGE:
There are two choices. When the box is not checked
(default setting), the Sample Rate is determined by the
Sample Rate Setting in the Wadia USB Control Panel.
It would be an appropriate choice when using a play-
back program like Windows Media Player.
If a third party program for music playback is
ASIO compliant then check the box. These programs
allow changing the Sample Rate Setting directly “on
the fly” according to the format of the music being
played back. An example of just one of the available
programs is “JRiver Media Center”.
