Each of these sound testing procedures tests your microphone and
sound card in combination. If you have several microphones or sound
cards, you can test each combination in turn, but there’s no way to test a
microphone or sound card independently. Sometimes a microphone
model that works well with one sound card will work poorly with
another. If you are using a USB microphone, the sound card is included
as part of the microphone and bypasses the sound card in your computer.
To test your sound system automatically:
1
Click Accuracy Center on the Tools menu on the DragonBar. The
Accuracy Center appears (as shown on page 152).
2
Click or say “Check your audio settings.” The Audio Setup Wizard
appears.
3
Follow the on-screen instructions as described on page 16. The wizard
will end with a measurement of sound quality, as shown below.
▲ This sample test result is for a sound system that is working well.
Acceptable values for the signal-to-noise ratio range from 15 to 30. If
your measured value is below this range, you probably need to change
your microphone, your sound card, or both.
