There does not seem to be a streaming sound recording I/O capability.  
(Maybe there is something in the video libraries, I don't know.)

Revolution does have the ability to record to a file.  (Not a variable, 
as far as I can tell.)  This recording is started with a command and 
stopped with a command.  I assume you can be recording to only one file 
at a time.  If that assumption is false, then you have more options.

A simple (and maybe too crude) method might be to have mic button as in 
half-duplex radio.  The mouseDown event could start recording and 
mouseUp could stop it and send off the sound.  This does not have to be 
half-duplex; the speaker could send sentences and receive sentences.

One problem is that the sound is delayed.

One way to avoid the delay is to record in small chunks and send that.  
I would expect you will get big parts missing and nasty clunk sounds.

Maybe it is possible to read the file as it is being recorded and send 
portions.

Communication needs to drop frames if the pipe gets too clogged.

It might be there is some command-line app that can do all the work and 
meet some standard and then all you have to do is control it.

These are very general.  Perhaps these are suggestions.
