[hpsdr] Fwd: Re: Balanced audio on future boards

[H.A.Meijer]

Hi Jim,

Yes, possibility's are endless.
But as already mentioned before, it can be done now,  just by using the VAC.

Let VAC 'talk' to a VST-host <http://www.audiomulch.com/> and then you 
can use all the now available (free) VST audio plug-ins 
<https://talkinmusic.com/musicproduction/top-100-free-vst-plugins/>.
What about powersdr having a simple VST-host build-in?.

Hi Bert,

I'd like to suggest that instead of PowerSDR connecting to the sound 
card directly that a network streaming audio interface be added
(if it doesn't already exist) that would allow developers to build apps 
on any platform to send/receive basic audio and PTT data using
an open-source audio compression codec.

The "remote" app could run on the *same Windows computer as 
PowerSDR* using an ASIO audio device, kernel streaming,
bluetooth headset etc. or it could be an Android tablet running remotely 
over wireless, a Linux desktop, a phone ... and so on.

Once the streaming interface was implemented, the PowerSDR developers 
could continue to work on PowerSDR, and other developers
could write nice audio interface apps for it. For example, I might be 
interested in writing a Windows and/or Linux app that would add multi-band
compression, parametric EQ and other features to the audio chain. I 
don't have the time or desire right now to be responsible for an entire
branch of PowerSDR, but I could be responsible for my own audio app, as 
could other developers.

Parts of it could be done right now using VAC to interface to PowerSDR, 
but that seems clumsy to me. It also wouldn't allow for PTT
without a virtual serial port, which again complicates things. Perhaps 
virtualizing the CAT command set using a separate socket or
UDP port along side the audio streaming might work.

Just thinking out loud...
