9.Rather, the analog audio waveform is placed on a graph, and all the values that it passes through at a set time interval are placed into a list of values.
10.I will also point out that, if the time interval over which the average velocity is taken is very small, then the velocity is considered to be an instantaneous velocity.
11.For other frequencies, though, even if you just increase it by a bit, this is cancelled out by the fact that for longer time intervals you're giving the wound up graph more of a chance to balance itself around the circle.
