    This sounds good.

    If a game is made using true audio tech it means it can reproduce far more accurate positional audio because it is getting the position data directly from the game.

    Yes that one wsa bout 2 months ago when they released the R9 cards. But it gives a good idea how it works.

    I've seen the conference live. While it does give a good idea about TrueAudio (10-12mins) the whole conference is not related!

    Yeah it means it is running a dedicated DSP (which is 3 Tensilica cores).

    Not quite on the same level as what MS is doing but then again MS is doing all that extra $#@! with Kinect and voice recognition. In reality this is should be as good as what MS is doing for gamers.
    Less work for the CPU to do is always good.

    More Info:

    Continuing our coverage of AMD’s APU13 conference, one of this morning’s keynotes has been from Sony’s VP of Research & Development in North America, Dominic Mallinson. Most of Dominic’s presentation was a recap of the PS4 thus far – including some detail in why Sony went with an AMD APU for the console – but Dominic did throw in one more piece of information on the PS4’s specifications that we haven’t heard before. Specifically, the PS4’s audio DSP is based on AMD’s TrueAudio technology.

    Briefly, from a console-centric view this isn’t of great surprise. We’ve had every reason to believe that the PS4’s audio DSP would have similar capabilities to TrueAudio given the features and low die space cost of today’s audio DSPs, coupled with Sony’s previous comments on the matter. So from that perspective this isn’t a significant revelation as far as the PS4’s audio capabilities are concerned, but we do finally have a bit more detail on the underlying hardware powering it.

    But from a PC perspective however, this is going to be more important and unexpected news. At this time we don’t know what the underlying API is like – AMD hasn’t even released the TrueAudio PC API yet – but the shared hardware is going to be a big deal for both AMD’s CPUs and APUs. One of the challenges we discussed as facing TrueAudio is developer adoption; AMD has to convince developers to take the time to program for TrueAudio along with more traditional CPU sound engines. AMD has been working with audio middleware developers to help bootstrap TrueAudio adoption, but today’s announcement would take that one step further.



    PS4 utilizing TrueAudio means there will be at least some level of audio engine portability between the PS4 and current generation AMD products. To that end if developers can write high quality audio engines on the PS4 thanks to the presence of the dedicated audio DSP, and then take that audio engine and bring it to the PC to run on GPU/APU TrueAudio DSPs, then that provides a further avenue for bootstrapping TrueAudio usage in games. So much like Mantle in the graphics space, a shared console connection for TrueAudio in the audio space would allow for AMD to leverage their console connection to both allow better/easier porting from consoles, and to achieve the critical mass necessary to make tapping these low-level hardware features viable and worthwhile for a wider pool of developers.

    That said, AMD isn’t promoting TrueAudio as a console porting solution right now like they have been Mantle, but the potential is there if AMD and developers seek to exploit it. Which if nothing else makes TrueAudio all the more worth keeping an eye on over the next year, as solving the bootstrap/adoption issue will be a critical factor in the technology’s success. On that note, according to AMD’s latest schedule Thief is still expected to be the PC TrueAudio launch title, so we should be getting to see the first fruits of AMD’s labor here in February.

    ..How come this wasn't unearthed until now? You'd think that someone would have leaked this or Cerny\etc would have spoken on it.

    Up until this point we simply thought it did compression\decompression and this fact seemed fairly solid and non-debatable. This was completely out of the blue for me.

    To be fair, they are saying its based on, and not "is" True Audio, they haven't really outlined the differences, but if they are minimal, then that's all good.
    True audio in itself isn't really anything new, DSP chips were a big thing in the 90's. As to why they hid it away, meh, I guess Cerny kind of alluded to it with saying the GPU could do the audio tasks.

    Sound in games these days has taken a back seat everyone seems to be graphics $#@!s, hope this changes that and we hear a good bump in auio fidelity and positioning.

    Please dont say "BF3 sound is amaizing" its not, the "war tapes" just amplifies everything and adds lots of reverb and the most important part; positioning is diabolically bad at times.

    So still nothing on fine details about the APU though? Quick look at live blogs of the presentation didnt go into any more detail that we already know.
