Slim PS3 Can Bitstream Dolby TrueHD Sound, Old PS3s Can’t

By Spencer . August 21, 2009 . 2:25am

image In addition to Bravia TV connectivity, a Slim PlayStation 3 with firmware 3.0 can bitstream Dolby True HD and DTS-HD Master audio.


Current PlayStation 3s, however, won’t be able to do this even after a firmware upgrade. A report from Impress Watch explains this feature is only available to slim PS3 owners due to hardware differences.


Every PlayStation 3 revision seems to lose some features and gain others. I wonder what the final version of the PlayStation 3 can and can’t do…

    “You can communicate to a new cyber-city, this will be the ideal home server. Did you see the movie ‘The Matrix’? Same interface. Same concept. Starting from next year, you can jack into ‘The Matrix’.”

    Never gets old. Yes it does, but what could I do?

    Kind of makes me wonder what else is in this new PS3 that Sony isnt telling us.

  • Not an entirely great loss unless you’re a hell-bent audiophile.

    Thankfully, I’m not one of them, but at least I have a semi-decent 2.1 system @ 450W strapped to this system. Haven’t really yet been able to invest in a decent surround sound for my big screen though in this economy just yet…

    I have a decent 5.1 surround system, but no higher than normal DTS. I guess this doesn’t affect me in the slightest.

    What’s the difference between PCM and Bitstream anyway?

    • Bitstream sends raw audio, unprocessed and uncompressed. PCM is converted, compressed, audio.

      Basically, you’re going to get better audio out of Bitstream…but in the long run it probably won’t make that much of a difference. Also, if you’re using analog, it won’t matter anyways and will probably sound better in PCM than it would in Bitstream in some cases.

      • Yopu have that backwards, Hiryuu.

        Bitstream codecs use lossless compression to send audio to the receiver from the player so that the receiver performs the conversion transparently.

        DTS-MA and TrueHD are used in place of uncompressed PCM audio to conserve space on the disc for other elements of the package. PCM is the highest resolution audio container available, but is also the largest in terms of size and is used only when space permits a full resolution 7.1 channel PCM mix.

        Neil Young’s recent Archives boxset release uses PCM audio almost exclusively for the highest audio resolution possible, which is actually straining some player receiver setups due to the amount of bandwidth being used since the audio resolution hits 24/192 Khz on Blu-Ray versions.

        • …I really need to re-look over my stuff before I write it down.

          My excuse is I was at work when I said that. :P

          • No problem. :) I figured you had them mixed up since you had the principle correct but you had your terms swapped. I may pick up a Slim for a straight Blu-Ray player/media center to complement my new Onkyo.

      • There’s usually not much point in wasting valuable disc space to store the audio uncompressed, if proper lossless compression of can easily be decoded by the player or receiver.

        Hiryuu? Haven’t I seen that name before?

          No, not all.

    Bummer, I wonder what other new features would the Slim have that old one doesn’t. If it somehow obtains B/C via future updates, then this would truly surpass the fat. Even though I’m kind of tempted to get this despite not being wowed by the design, I can’t get rid of the fat since I only have a Jpn PS2 slim.

    At least this Dolby thing doesn’t concern me at the moment since I can’t crank up my speakers to disturb the neighbors anyway, maybe when I have a house on my own later..

    I’ve alrdy upgraded my 60 to 320gb, I wonder if moving the 320 to the slim would make its fan noisier.
