摘要： The system and method of the present invention rely on combining the Speakers+Room binaural Impulse Response(s) (SRbIR) with a special kind of crosstalk cancellation (XTC) filter—one that does not degrade or significantly alter the SRbIR's spectral and temporal characteristics that are required for effective head externalization. This unique combination leads to a 3D audio filter for headphones that allows the emulation of the sound of crosstalk-cancelled speakers through headphones, and allows for fixing the perceived soundstage in space using head tracking and thus solves the major problems for externalized and robust 3D audio rendering through headphones. Furthermore, by taking advantage of a well-documented psychoacoustic fact, this system and method can produce universal 3D audio filters that work for all listeners i.e. independent of the listener's head related transfer function (HRTF).
