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.

What is Spdif out used for?

SPDIF is a standard for transmitting high-quality digital audio without going through an analogue conversion process. It is used for connecting Hi-FI Equipment, DVD players, CD players, Mini-Disc Players, Sound cards etc. This interface uses RCA phono connectors and 75 Ohm coaxial cable.

Is PCM 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. … Dolby Digital® technology uses a 5.1 or six channel format.

What does PCM mean in sound?

pulse-code modulationPCM: 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.

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.

What is ARC audio output?

Audio Return Channel (ARC) is a type of audio transmission that links up your speaker output to your television controls, meaning you don’t need a separate remote or interface to manage the volume.

Which is better 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.

Which is better Dolby or PCM?

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 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!

Which audio connection is best?

Both HDMI and optical digital audio from one device to another are better than analog that can pass multi-channel audio. Both of these cables had pretty cheap. However, the simplest advice is to go with HDMI. The biggest difference is that HDMI can pass the higher resolution audio such as formats found on Blu-ray.

What is HDMI ARC?

HDMI ARC is designed to reduce the number of cables between your TV and an external Home Theatre System or Soundbar. The audio signal is capable of traveling both ways to and from the speakers, which will improve the sound quality and latency of the signal.

What is the 1 in 5.1 surround sound?

A surround sound system that uses five audio channels plus a subwoofer channel (the “1” in 5.1). Widely used in home theater systems, DVDs are often recorded in 5.1 audio encoding technologies (see Dolby Digital and DTS). For more speaker configurations, see home theater speakers.

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.

Is Spdif better than optical?

They are both digital connections. Optical usually refers to the ADAT protocol over a fiber optic cable (TOSLINK), while SPDIF is usually transmitted over a coaxial “RCA” cable. “Usually”, optical can carry 8 channels at 44.1/48KHz (or 4 at 88.2/96KHz in certain situations) while SPDIF is stereo (two channels).

Is DTS or Dolby better?

DTS is encoded at a higher bit rate and therefore is considered by some experts to be better quality. Others argue that Dolby Digital’s technology is more advanced, and produces better sound quality at a lower bit rate.
