Hello Steve. I am absolutely NOT an advocate of smashed broadcast audio, but we should recall that radio operates through two imperfect mediums...the transmission path where natural and electrical noise beat up the signal, and the ambience in which the receiver is located, where the station must sometimes fight for attention. (The automobile might be an example. ) Regards, Mark Durenberger, CPBE -----Original Message----- From: Steve Greene Compression is a tool used all the time on radio. In fact radio may be a prime driver of the trend. Steve
