In basic terms, a PCM audio file is a digital interpretation of an analog sound wave.

The goal is to replicate the properties of an analog audio signal as closely as possible.

Analog-to-PCM conversion is accomplished via a process calledsampling.

Analog sound moves in waves, as opposed to PCM, which is a series of ones and zeros.

In other words, the digital audio standard for CD audio is 44.1 kHz/16 bits.

When used in surround-sound applications, it’s often referred to as linear pulse code modulation (LPCM).

In addition, most DVD and Blu-ray Disc players can transfer PCM signals via an HDMI connection.

Check your player and stereo or home theater receiver for your connection options.
