Real-Time Auralization with Head Tracking

Room auralization (Kleiner, 1992) is a process by which live or recorded sounds can be presented to a listener so that the listener perceives them to be localized in a specific point in space, in a specific room environment. This is achieved by modeling the entire acoustic transfer function between the source location in the room to the listener's eardrums. This technique can take every detail of the acoustic space into account, including the loudspeaker or headphone-to-ear transfer function. The model can be implemented in real time, with no extraneous latency, using Lake's Huron convolution techniques. The work presented focuses on how these techniques can be modified to accommodate rotation of the listener's head, while maintaining a spatially located room experience.:
