sample rate -- the number of measurements per second
bit depth -- the number of steps away from silence for each sample
bit depth (amplitude resolution) is an interesting concept in relation to
sampling since its the real content of a digital stream of audio. the sample
rate is not represented implicitly in a stream of large numbers, it is
understood beforehand. each sample in the steam is an actual plot some
distance away from 0 (silence), either positive or negative. these
measurements come at a predefined rate per second (sample rate). you
can visualize this best with a grid, where the horizontal lines represent bit
depth (Y axis), and the vertical lines represent sample rate (X axis).
