You're confusing sample rate with frequency response. The more samples, the smoother the waveform curve. Remember, there's no such thing as a curve, a curve is just a bunch of connected points where each point is slightly angled from the last. If there are more points, the curve is, well, curvier. If there are fewer points, the waveform actually displays as many, many short little lines connected together, and since your ear is logarithmic, not linear, you can tell the difference by the way the audio in the waveform changes with respect to dynamics and definition.
Frequency response is the measure of audibility of a waveform going from the bottom of the curve to the top of the curve in a given period of time--8khz per second means that the waveform goes from 0 to full eight thousand times per second. However, if you were to sample a tone of 8khz 44,100 times per second, you'd get 44,100 little slices on the curve, but only eight thousand peaks along the map of that curve for one second. If you do a little cheapy finger math and round the numbers a bit, it would take approximately five samples at 44,100 hertz to sample one cycle of a sine at 8000 hertz. The actual number is 5.5125, but since there's no such thing as a partial sample, only a partial curve, which means a partial amount of data that can be sampled within a given time period, you have to do some tricks to make the human ear ignore the missing portions of data caused by the oddball math. This is why digital audio repro doesn't sound like analog repro. On Fri, 06 May 2011 21:49:43 -0700, you wrote: >Um, let me ask more about bit and Hertz.
