Binaural recordings must be headphone-based because cross-ear coupling destroys the illusion
Evidence
To convert normal stereo signals into signals suitable for binaural presentation, it is necessary to filter the left and right channels with the HRTFs associated with the positions of left and right speakers, as shown in Figure 7.15. Note that four filters are involved, because one must model not only the transfer function to each ear but also the cross-coupling of the loudspeakers between the two ears. — David M.
