I agree with the comments by Steve (Audioengr) and Mapman just above. One further point:
To put things in perspective, it's perhaps worth noting that each of those increments is small enough to represent 0.0015 percent of the maximum possible ("full scale") amplitude.

02-05-14: CzariveyAs you may realize, the vertical (amplitude) axis is divided into 65,535 portions (increments), not 16. For 16 bit data, there are 65,536 possible amplitude values (corresponding to 2 raised to the 16th power), which means that there are 65,536 - 1 = 65,535 increments.
With vertical axis not everything is perfect either. For red book CD we have 16-bits resolution. It tells you that maximum amplitude is 16 bits and the whole dynamic range is divided by 16 portions of the vertical axis.
