This is an older YouTube video, but I have only recently come across it, and I thought I'd share it with the folks here on Head Fi. If you've heard it before, my apologies for reposting it again. (I did a couple of quick searches and couldn't seem to find anything similar here.)
The reason I came across this is because of AMD's recent announcement for TrueAudio integration in their next gen CPUs, except that the audio is processed in real time instead of pre-rendered as it is done here in the YouTube. Pretty cool stuff...
For those who haven't heard the above audio before, I won't spoil it for you, but the 2nd half of the demo is really, *REALLY* impressive. It sounds so incredibly realistic on my DT880 that I was creeping myself out.
