thought HD was digital sound ???

[Stu123]

just read this in a forum and i thought the HD codecs were digital sound now im confused

Dolby TrueHD and DTS-HD MA compress the LPCM audio signals without any loss of original data in order to save space on a disc. When the saved signals are decoded and decompressed, we will get LPCM signals again.

If the disc player decompresses and decodes the compressed audio, it will send the LPCM signals to the receiver. The receiver will then covert the LPCM signals from digital to analog for playback through the speakers.

Exactly.... because your speakers can't play digital signals they MUST be converted to analog. It's always been this way... with DVD's, CD's or any digital source. Your receiver has DAC's (digital to analog converters) for this very purpose.

So they call it dolby digital but you're not really hearing digital? i need some fresh air

The source is indeed digital and "pure" but speakers are analog equipment. The digital signal must be converted to analog, but that does not mean that it is degraded or corrupted in any way whatsoever.

Yes it is digitally recorded on the disk as opposed to analogue cassette tapes or vinyl records. The player plays back the digitally encoded (e.g. DTS HD-MA) bit stream and it is carried over HDMI cable on to the receiver. The receiver decodes (DTS HD-MA to PCM) and coverts (PCM) digital bits into an analogue signal (using a DAC) and feeds into the analogue amplifier and to the speakers. In principle it is a simple process. (In some cases the player decodes DTS HD-MA to PCM.)

unless you can ear "0100111110110" sound from the speaker, yeah it's analog

There is no such thing as "digital" sound. Audio information can be stored in a digital format, but it needs to be converted to analog at some point so speakers can output sound and you can, you know, actually hear it.

I thought I was the only one!

Actually, binary in sound form would probably sound like morse code except way more unintelligible. You wouldn't hear "one" and "zero", it'd be a tone or lack-of-tone.

[QUOTE=Tinman7783;2338385]My receiver Sony STR-DH700 7.1 ch does DTS but technically not Dolby HD. I know DTS MA is backwards compatible and this explains why my Bluray movies with DTS MA sound amazing. My question is when playing Bluray movies with Dolby True HD my receiver display states dts 3/2.1 and it sounds great much better than regular Dolby Pro Logic, is this HD audio? To achieve this I make sure at my Bluray player LG BD 370 I choose the HD audio option. The receiver does 8 channel LPCM is this way? B/c all audio signals are converted to LPCM anyways?
