An interview reveals that there's a few drivers in the headphones, placed around the ears, a technique used in some 5.1 gaming headphones.

XTC is not specifically for binaural recordings; it expands the stereo image of any stereo feed. It's a lot of fun to rediscover old record collections... It helps to localize sounds in a complex stereo scene, and I prefer it to headphones because it provides a frontal scene instead of an "in head" scene. The BACCH filters are excellent, but they are not free. Impulse responses from David Wareing are free, but EQ is required (more LF, less HF): http://www.wareing77.plus.com/Filters/ I combined them as a "true stereo" filter for a reverb convolver. I use it with my laptop and a pair of small USB speakers. It's perfect for long computing sessions. The best method is a physical barrier, something that very few people on earth would install in their living/listening room (I did for a few months). > www.astoundholdings.com > > > GenAudio created AstoundSound as a software solution.

I just tried the demo. It works very well for interactive audio. -- Marc _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
