PCM is better for TV speakers, while Auto is better for external speakers or home theater setups. PCM sends uncompressed audio in the stereo (two-channel) track, while Auto generally uses Dolby Digital tracks, wherein the audio is compressed and sent through a multi-channel track.

Is PCM audio high quality?

PCM (pulse code modulation) is the “raw” signal generated by the AD converter. This means that the signal is not additionally source-coded by, for example, DTS or Dolby Digital, and is therefore not converted. As PCM, your signal is pure and usually in the highest quality.

What is PCM audio

What is the best PCM format for audio?

The best audio formats for sound quality are uncompressed or lossless compression files—think WAV, FLAC, and M4A. That's because these formats retain the original sound quality, though you'll have to put up with the fact these files will be large.

Can PCM do surround sound?

PCM doesn't support surround sound. No wireless audio support. Digital optical and coaxial output has limited capabilities with PCM. PCM can only use a two-channel signal.

Is Dolby Digital PCM?

When should I use PCM?

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. Note: This changes the signal to 2.0 PCM as it passes through the TV.

What is the most common PCM format?

There is a subtype of PCM called Linear Pulse-Code Modulation, where samples are taken at linear intervals. LPCM is the most common form of PCM, which is why the two terms are almost interchangeable at this point.

What format is surround sound music?
