Audio Sample Rate
Analog signals are described by a continuous fluctuation of voltage. The analog signal is converted to a digital signal by being measured periodically, or sampled. If you think of the original audio as a curve, the digital audio would look like a connect-the-dots version of that curve (Figures 18.28 and 18.29). The more dots (samples) you have, the more accurately you can reproduce the original curve.

Figure 18.29. Digital audio samples, or measures, the audio at discrete intervals.
