Uncompressed or Dolby Digital? - Blu-ray Forum

Zaphod · 07-21-2007, 10:37 AM

Uncompressed is definately the best you can get when it comes to audio...right now. PCM stands for pulse-code modulation, which is what uncompressed is sent out as from the PS3. The other type is bit-stream which is sent out via optical on the PS3.

You can re-watch it with DD, but after the first 5 minutes you will realize that uncompressed PCM will not be beat!

Welcome and as a side note we are not all like BozQ and give such smart ass answers to legitimite questions.

Uncompressed PCM is basically the original master.
The Dolby Digital track is there to provide folks without HDMI audio a way to get 5.1 surround sound thru the optical digital output. It's backwards compatible with basically every surround sound receiver made in the last 10 years. DD takes up very little space, is very efficient, and mandatory for DVD and HDTV. But if you have the means, uncompressed is the way to go.

I totally agree with the bolded text

However, there is a slight correction for your statement. You can output bitstream over HDMI as well. This way the receiver will decode the audio for you. This is only possible for DD and DTS though, you cannot bitstream DD TrueHD or DTS HD Master Audio,... yet.

Sorry...and thanks for the correction HDJK.

To the OP: If you have a HDMI receiver capable of passing through video and amplifying audio, set the PS3 to Multichannel LPCM under Audio->HDMI.

We need a NEWBIE sticky for BD player setups.

Zaphod, and everyone else who responded, thanks a ton for answering my question. I am glad I made the right decision and watched the movie with uncompressed audio. I'll never go back to DD with Blu Ray. I'm assuming uncompressed is an option of all BD movies. Thanks a ton in advance folks!
