PCM audio (Pulse Code Modulation) is a process that is utilized to convert analog audio signals that are represented by waveforms to digital audio signals which are represented by ones and zeros without neither compression nor loss of information. PCM audio is the audio standard for all digital consumer formats such as CDs, DVDs, Blu-Ray Discs, etc.

PCM (Pulse Code Modulation): a system for representing a sampled signal as a series of multi-bit words. This is the technology used in audio CDs. PDM (Pulse Density Modulation): a system for representing a sampled signal as a stream of single bits. Sampling rate is the rate at which a signal is sampled to produce a discrete-time representation.
