    Even easier, the few NPR podcasts I just checked now have RSS
feeds of their episodes (as expected).  It seems it would be much
easier to just download the latest episode based on the XML file,
normalize, send it to play, done.

    Why is it so crucial that it be done "in real time", which it
really isn't, unless you are listening to the live NPR feed.  In the
case of podcasts, *why* would you possible play them via streaming
instead of downloading the publicly accessible file to manipulate
however you chose?

    Based on what?  Do you want a 10 second buffer to continually be
analyzed in real time?  From the output of a speaker, no less? 

    And which level?  Peak?  Average over...10 seconds?  Are you
keeping track of the previous values to make it match?  Where is that
stored?

    OK...then perhaps I/we am/are confused on the limitations of the
program.  What does it "grab", *exactly*?
