I can have jimbopyana speak into a microphone and have the sound of a jackass braying come out of the speakers instead of his, no doubt, mellifluous voice.

I can set up a mic to capture the sound of a baseball bat hitting the ball and altering it to a cat screaming, right now, this mini-second, as it occurs, immediately, before the swing is complete.

We agree and I'm arguing semantics. It can be perceived as instantaneous but there is a lot going on between the time you receive your input signal and the time that the final audio is ready for broadcast. Of course, we're talking about high-speed processors that can accomplish these feats in milliseconds but just because we can't detect it doesn't mean it's not happening.
