What does PCM stand for audio?
Pulse-Code Modulation
Pulse-Code Modulation (PCM) and the Dolby Digital® technology refer to different types of digital audio recordings. PCM is the conventional method for converting analog audio into digital audio.
What is TV PCM setting?
PCM: This stands for “pulse-code modulation.” Use this setting if the external device you’ve connected to the HDMI port has already processed the sound, and you just want it to come out of your TV’s speakers. We recommend to select PCM when using the TV’s speakers.
What is PCM audio used for?
Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications.
What are channels in audio?
A channel is a representation of sound coming from or going to a single point. A single microphone can produce one channel of audio, and a single speaker can accept one channel of audio, for example. A digital audio file can contain multiple channels of data.
Is PCM better than Dolby?
Pulse-Code Modulation is the typical method used for converting analog audio into its digital counterpart. When you see PCM audio on a DVD, it’s a two-channel stereo digital audio track. From a technical standpoint, most people would consider PCM to be worse than Dolby Digital because it offers fewer channels.
What is better PCM or Dolby Digital?

How many channels does a PCM signal transmit?
1 PCM transmits a two-channel signal over digital optical or coaxial. 2 Audio quality is partially determined by the player (Blu-ray player or any player). 3 More work is done by the player.
How does a PCM convert an analog signal to digital?
PCM Audio In basic terms, a PCM audio file is a digital interpretation of an analog sound wave (1) whose goal is to replicate the properties of an analog audio signal (3) as closely as possible to the original source (4), called fidelity (2). The conversion from analog to digital PCM audio is done through a process called sampling (5).
What is the difference between PCM and Dolby Digital?
Pulse-Code Modulation (PCM) and the Dolby Digital® technology refer to different types of digital audio recordings. PCM is the conventional method for converting analog audio into digital audio.
