That will perform the same functions as FM Radio Transmitter limiters. As in that post, music and comedy programs sound exactly like the local FM station, minus the stereo intercarrier hiss. Just add a bit of pink noise to the background and you got it.
I discovered this process when I went from off-air KPCC to internet download of “Car Talk,” among others. The sound quality skyrockted and the transmitter fffffffff vanished, but I was presented with the raw studio sound. One of the presenters mumbled in his beer and the other had a thermonuclear laugh. Can’t listen in the car, pretty much the problem that Chris had.
Problem solved. Pay attention to that end-of-show bug.
I don’t put the hiss back.
