More Reading: Information about PCM and WAV

PCM (Pulse-code modulation), which is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu-ray, DVD and Compact Disc formats, as well as other uses such as digital telephone systems. PCM streams have two basic properties that determine their fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit depth, which determines the number of possible digital values that each sample can take.

The WAV format is the format of Microsoft in partnership with IBM in the 1990s. It remains the most common format for saving and exchanging uncompressed audio. Like some older formats, such as the Red Book format used on compact discs, WAVs are based on pulse-code modulation. PCM imposes certain limitations on the number of channels and the sample rate of the recorded audio. However, further iterations of the WAV format removed some of these limitations.
