Worth noting that this kind of processing has been present on some PC soundcards for a while. Creative has its 'surround' processing for the Z series and a similar feature whose name I forget for the x-fi series. Processing done in hardware. Dolby also has its own virtual surround processors that come with some of Asus' Xonar offerings. I'm not sure what degree of processing is done in hardware/software. A lot of home theater receivers also support pro-logic. I've bought a few x-fi's and a SBZ just for their surround abilities alone. A youtube video I found comparing the above techs doing stereo->headphones: https://www.youtube.com/watch?v=Y6ROujJ8Ae8 https://www.youtube.com/watch?v=Y6ROujJ8Ae8 I know the Creative cards can work off a multichannel input as well, not sure about the Dolby tech.

Haha yes you're absolutely spot on. The knowledge on how to do this has been around since 1988: http://staffwww.itn.liu.se/~karlu/courses/TNM086-2011/papers/localization.pdf http://staffwww.itn.liu.se/~karlu/courses/TNM086-2011/papers... I tried out Dolby's Headphone offering a while ago and I just didn't like the way it sounds. My guess is that they are using equalizers to fake the FIR filters without accounting for the delay-dependent part of the EQ. But that's just my speculation. I didn't know that Creative was offering this, too. BTW, I believe that the Razer Kraken 7.1 Headset is technically also just a stereo USB headset with an app not unlike mine.. but that is also just my speculation, as I didn't try out their product yet.

  Yeah, I agree the Dolby headphone tech isn't quite right. But the Creative one has really impressed me over the years. I've even panic muted my speakers before when I was wearing my headphones because I thought I forgot to switch outputs. Unfortunately, I don't have a Mac, so I can't compare it your implementation.
