[hpsdr] ozy/janus as soundcard for digital modes

[george byrkit]

Stephen,

The point you keep missing is that Ozy/Janus audio is designed to be I/Q
audio (RX/TX), possibly with provisions for RX monitoring in normal audio
space, just as Mercury has 'normal' audio out to plug into speakers or a
headphone to allow you to listen to the audio.  But that's it right now
unless YOU write some code...  We are long on requests from the community,
and short on people to implement them!  So if you have a request, please
don't be surprised when/that we ask you when/if you want to implement it
yourself.

So all the programs that use Ozy/Janus (on windows, that would be PowerSDR
and KISS) believe that only I/Q audio will be supplied as input to
decode/demodulate.  And more specifically that such I/Q data represents a
chunk of the RF spectrum that is either 48 khz, 96khz or 192khz wide.  You
could take PowerSDR or KISS and modify them heavily to only pass data on to
something else, possibly via VAC, but that would be a lot of work.  KISS
doesn't support VAC or JACK or similar.  PowerSDR supports VAC but does NOT
support viewing the audio in as 'normal' audio (rather than the I/Q RF data
which it expects.)
