General audio topics that don't fit into specific categories.

You're not trying, guys

Try to think back, i knows it's hard for you, we were talking about the signal in cables, not acoustic waves, Mr. Smarty Pants. I realize I'm not dealing with the faculty at Harvard here, but come on guys, at least try to keep up. You're not trying.

Of course, it should be noted there is an "instantaneous frequency" for an acoustic wave, too, for any wave. Mathematically instantaneous frequency is a differential equation involving time and phase.

In audio cables like speaker cables, for example, the audio signal from the source, CD, LP, cassette, DICTATES the ALTERNATION (that word means how fast it alternates) of electron "movement." I put movement in quotes because electrons only move about a millionth of an inch at a time, electrons wiggle back and forth at audio frequencies. Follow?
