[R] real time monitoring of streaming audio with R?

[Spencer Graves]

Hello, All:


       Is it feasible to do real time monitoring of streaming audio with 
R, writing a compressed copy of what's read to 1-hour long MP3 files?


       I'm a volunteer with a community radio station (kkfi.org).  My 
minimum requirements at the moment are to create MP3 files from what we 
broadcast.  I have a tuner hooked to the audio input of a computer.  I 
can listen to it in real time using the computer audio output jack, and 
I can record it manually using Audacity.  If I have MP3 versions of both 
what we send to the tower and what is actually broadcasted, I can read 
the two into R, compare them, identify substantive differences, write 
appropriate descriptions to files, send emails, etc.  I don't know how 
to sample the live stream.


        I know it can be done in Python, but I don't know how, and I'd 
prefer to use R.  I suspect it can be done with ffplay, part of ffmpeg, 
but again I don't know how.


       Thanks,
       Spencer Graves
