The demodulator set-up window opens, as shown:
The Wave device drop-down list shows all the installed wave devices:
Windows default is the Control Panel setting specified under Start |
Settings | Control Panel | Multimedia Properties | Audio. If a sound card
is specified in this Control Panel setting for both playback and recording (this
is very likely, but not always necessarily so), then you can simply select
Windows Default as the wave device for the demodulator. Otherwise, the
specific name of the sound card should be selected.
The selected sound card must support duplex operation and the standard
44100 or 48000 samples/second sampling rates, 16 bits per sample, stereo.
Most modern sound cards do satisfy all these conditions, but some cards
may have a high level of distortion at 48000 samples per second; for such
cases, the 44100 samples/second sampling rate is provided.
