I just got a cassette from a co- worker. It's a tutorial on religious chanting with a female presenter with what sounds like a fairly pleasant voice. The level is very low (almost in the cassette tape hiss noise floor) and also very "distant" sounding, with lots of natural room reverb (which is probably a church, from the sound of it) You can guess how pronounced the reverb must be, if you can barely hear the intended direct sound above the noise floor.
After citing an example of chanting, the choir demonstrates- probably miked with overhead hanging condensors which is typical. Loud and Clear! Then back to the presenter with the barely audible voice. My guess is the recordist neglected to turn on the presenter's mic, and she was mearly being picked up by the hanging choir mics. This goes on back and forth for about a half an hour.
I better get two free tickets to Heaven for fixing this one. (I may want to bring a friend) I'm certainly not going to pass "Go" and I won't collect $200.
