I am interested in developing an audio editor for UNIX machines and would
like any information about existing audio to rs-232 convertors or the
possibility of building one.

I am not a hardware person, but wouldn't the device consist of mostly of
a couple of analog-to-digital converters whose digital outputs are
connected to the RxD pins of a couple of SCC's? RS-232 to audio could be
accomplished similarly: TxD pins connected to digital inputs of a couple of
digital-to-analog converters.  At a sample rate of 19200 Hz, I could
easily get a broadcast quality recording.

It would probably also require some RAM/ROM and a fairly stupid processor
(for initializing the SCC's and for handling the interleaving of data for
the right and left sides) and a third SCC for communication with
the UNIX machine.

I would like to be able to plug two microphones directly into the
audio-to-rs-232 device and connect the rs-232-to-audio device into
the AUX inputs of my receiver via standard interconnect cables.

Any information on this subject would be greatly appreciated!
