PHRTF: Efficient personalized HRTF
computation for high-fidelity spatial sound.
We have shown that the ambiguous interpretation of the HRTF
phase data is probably the reason for the oscillatory behaviour of MAA as a function of frequency in human performance.

The synthesis stage can also be easily implemented in real time since its main operation is amplitude panning (or HRTF
filtering for binaural reproduction).

As one might expect, the most effective 3-D simulation is usually obtained using HRTFs

revenues are required to be paid into the Commonwealth treasury and credited to the HRTF
on a monthly basis, subject to appropriation by the general assembly.
Additionally, the iMix 5.1 Monitor works with any type of headphone, including open-backed, closed-back, in-ear or ear buds without the need for individual HRTF
calibration or special setup.
It also includes an external Massachusetts Institute of Technology Media Lab HRTF
(head-related transfer function) library (Gardner & Martin, 1994) to increase the accuracy of the final localization.
Although spatial audio technology was used as early as World War I to aid in the detection of enemy aircraft (see Wenzel, 1992, for a brief history), it was not until the 1980s -- after the development of powerful digital signal processors and head-related transfer function (HRTF
) filtering techniques -- that virtual spatial audio displays could be generated in real time for headphone presentation.
