Part Two -- The Recording Chain- examines the steps that music goes through from performer to listener. This is a simplified version, since real-world recording is usually a lot more complex than this. Follow the twelve part series from renown engineer Doug Fearn as he takes us through the recording process and to your speakers.

It's basic concept is DeltaSigma modulation and uses 1 bit per sample with a sample rate of at least 2.8224MHz (64 x 44.1kHz).   Read the entire white paper by Andreas Koch, one of the pioneers of digital recording.  Download the PDF.

So what happens when two frequencies in the megahertz range are within beating distance? They behave in exactly the same manner as two strings. The periodicity of the beating generates a fundamental that occurs within hearing range.  Noise is a cloud of frequencies. As a result there are myriad frequencies interacting, generating a myriad of audible fundamentals.  Joe Cohen of the Lotus Group presents his explanation of how overtones / harmonics affects a manufacturer's design decisions.
