[hpsdr] Janus as sound card

[AA8K73 GMail]

Chris, when the Janus was designed, it was a replacement 
Analog-to-digital and Digital-to-analog device for I and Q 
processing for the Flex-Radio SDR-1000.  You could use a PC 
sound card to process the I and Q signals for the SDR-1000. 
This group started as a way of seeing how much performance could 
be improved if we bypassed ordinary and higher-end sound cards 
and went for maximum performance.  The group was originally 
called Xylo-SDR, and changed to HPSDR and then forked into 
OpenHPSDR.  Guys in the group looked at making Janus act as a PC 
sound card, but the machinations needed to be a "sound card" for 
Microsoft Windows was a lot more effort than anyone was willing 
to devote to the project.

My SDR-1000 did indeed perform significantly better with Janus 
than with my M-Audio Delta-44 PC sound card.

Current software has dropped Janus/Ozymandias support, so the 
card is not as useful as it was.
