What Is The Difference Between PCM And Raw Audio?

What is raw audio on TV?

RAW Audio format or just RAW Audio is an audio file format for storing uncompressed audio in raw form.

Comparable to WAV or AIFF in size, RAW Audio file does not include any header information (sampling rate, bit depth, endian, or number of channels).

Data can be written in PCM, IEEE 754 or ASCII..

What’s better Dolby Digital or PCM?

Distinguished Member. Dolby Digital is compressed so PCM is better. Dolby True HD, DTS HD MA, Atmos and DTS X are also lossless, so should be similar quality to PCM. If the source audio is stereo, it should only be coming from your front left and right speakers unless you use an up mixer.

What is PCM and Raw?

PCM is indeed pulse code modulation (though PCM itself can be 2 channel or multi-channel). Its the basic form of digital audio, and its what conversion and processing chips usually use. … If you output raw audio (often called bitstream) then the receiver will do that.

What is raw setting on TV?

Raw is for ‘bitstream’. It will pass DD, DTS or PCM stereo. PCM is for PCM stereo only. So it should be set to RAW. Thanks for the info!

What is Spdif PCM?

0-9. (Sony/Philips Digital InterFace) A serial interface for transferring digital audio from CD and DVD players to amplifiers and TVs. S/PDIF is typically used to transmit PCM and Dolby Digital 5.1, but it is not tied to any sampling rate or audio standard.

Is Optical better than HDMI?

Both can pass multi-channel audio, like Dolby Digital. Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio. These formats can’t get transmitted across optical.

What does PCM mean in sound?

Pulse-Code ModulationPulse-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. The PCM audio recorded on DVD is a two-channel digital, stereo audio track.

What is Spdif audio out?

S/PDIF (Sony/Philips Digital Interface) is a type of digital audio interconnect used in consumer audio equipment to output audio over reasonably short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fiber optic cable with TOSLINK connectors.

Should I use PCM or Bitstream?

Bitstream is better, but for stereo source it is basically the same, except if your sources pcm decoding is bad somehow. For newer audio formats is bitstream always better. Up to 5.1 sound it’s your decision pcm or bitstream, over that choose bitstream.

What is a Spdif connection?

S/PDIF (Sony/Philips Digital Interface) is an audio transfer format interface. It transfers digital audio signals from one device to another without the need to first convert to an analog signal, which can degrade audio quality.

Is PCM good sound?

PCM is generally a high-quality stereo (2 channel) format. This would be appropriate to send to most soundbars which are also stereo playback devices. If your soundbar supports surround or virtual surround, you should be sending a digital surround format that it is able to decode.

Is PCM 5.1 surround sound?

PCM is uncompressed and can pass a full 5.1 signal. However you would need bitstream to pass any HD sources to a receiver from an Xbox or blu ray player to allow DolbyTrue HD or DTS MA HD, which is usually of a better quality than standard Dolby or DTS.
