[App_rpt] Recording repeater audio

[David McGough]

Jon,

I agree. In my experience, most any recent CPU has enough horsepower to 
easily keep up with real-time mp3 encoding.....Particularly if you aren't 
trying to encode "audiophile" quality mp3's! ....I haven't tried to get 
asterisk to do this, though.
