Is PCM the same as Bitstream?

Bitstream audio means the receiver will decode all the sound, this is generally the easiest option for newer AVRs. PCM means the device itself decodes the sound and sends it. It's exactly the same sound either way.

.

Consequently, what's the difference between PCM and bitstream audio?

For digital optical/coaxial connections, while the bitstream output option can send a standard Dolby Digital or DTS 5.1 surround sound signal to your receiver for further decoding, the PCM option will only send a two-channel signal.

Beside above, what is bitstream audio out? Bitstream encoding is a core technology that is used in home theater audio. It provides a way to transfer data-heavy surround sound information between a source device and a home theater receiver or AV preamp/processor within a narrow bandwidth using a variety of connection options.

Thereof, what is PCM audio on TV?

Pulse-code modulation, abbreviated "PCM," is a form of digital signal that is used to represent analog data. Depending on the model of television you watch, switching the audio output to PCM may improve the sound quality of the television's speakers.

Is PCM surround sound?

PCM can carry surround sound, but it cannot do so over an optical cable—the optical cable can only carry stereo PCM (using TOSLINK, the home stereo standard). To send surround PCM, you'd need to use an HDMI cable (or alternatively displayport on a PC), which carries both the video and audio signal.

Should I use PCM or Bitstream?

In this case pcm is better and only option. 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.

Is Bitstream better than uncompressed?

The older, more common bitstream formats (Dolby Digital, DTS) feature lossy compression and are limited to 5.1 channels so uncompressed PCM sound is superior. DTS and Dolby being lossy doesn't mean you are gaining anything by first uncompressing them and then passing over.

What is the best HDMI audio format?

The highest quality possible for ARC is DTS and DD/DD+. If you are plugging your android box into your tv you should use passthrough for everything up to DTS, then send anything higher (i.e. the lossless) as 7.1 PCM and set your tv Digital Output Audio Format to DTS.

What's the best audio format for ps4?

And QUESTION TWO: after extensive Google searching, it seems the consensus is that Linear PCM is best for HDMI/5.1/7.1 sound for "lossless" audio, but why is it that Bitstream (Dolby) sounds "best" to me – and I mean "best" because in most games, using that setting has a more "real" surround sound effect.

Is optical audio better than HDMI ARC?

Both are better than analog (the red and white cables). 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 PCM or Dolby Digital better with soundbar?

Dolby Digital is better. PCM is effectively stereo only. You'll get better definition out of Dolby Digital.

What does bitstream Dolby mean?
