Sorry if I'm stating the obvious, but FWIW: no, not obvious at all, a good reminder how just how much of this i "used to know". grin there has been surprising little interest in my post, i may try it again, any suggestion as to group/s? the pro audio is moderated and doubtful of any devices like these. Best Regards, and thanks, --Loren (a) Expanding low-level audio may cause you to hear some hum and hiss that were inaudible before.(b) Compressing high level audio sometimes results in distortion on the first few milliseconds of each audio passage. (c) If there's any contant background audio (crowd noise, nature sounds) in a signal that's being companded, the background varies, often annoyingly so, in a phenomenon called "pumping". Thus, you may need to limit the amount of companding. (In my experience, once you record something with pumping on it, you are stuck with it.) Good luck. "Sal" |
