Hey this would be a good one.
Hopefully the RPI could keep a constant waveform going out so not to
cause some sort of mis-modulation calamity. We've been running a full
PC with an M-Audio Audiophile-192 doing this for some time now with
fabulous results, but using a Windows processing software solution. It
would be nice to have a simple RPI thing laying around that could be
substituted in for a failed processor at any time. I don't know what
MPX code is around that will run on an RPI, isn't "StereoTool" a
commercial binary-only product? Someone did some simple source code
awhile back that just does the stereo MPX generation from two channels
of audio input, I have a copy of the source code for this. I was hoping
to adapt it to have a Jack Audio input so I can then use processing
elements already available to Jack (limiters, compressors, gates, EQ's
etc), to build a full stereo processor solution but such a task is a
little beyond me.

Do you know of any audio chip that would be able to handle 192kHz
sampling on a Pi 2 ? I'm thinking of building IP MPX codecs on raw PCM
between sites. I was thinking using old-fashioned E-MU 0202 for that
job, but maybe there are other solutions ?
Cheers !
