... second)6.1
An interesting side tangent from an Electrical Engineering giant named Nyquist: With digital sampling schemes, the maximum audio frequency that can be reproduced is half of the sampling rate. Thus, with a 48KHz sampling rate, a 24KHz audio signal may be represented. The range of human hearing is approximately 20Hz to 20KHz, so as you can see the range is well-covered. Audio purists argue that even 48KHz isn't a high enough sampling rate because sampling can't capture harmonics (multiples of frequencies) above the range of hearing, which may not be audible but still perceivable to humans. Most other people just shake their heads and don't really notice the difference.
