ABSTRACT
Binaural technology is the solution for sound spatialisation which is the closest to real-life listening. Various means have been investigated to minimise the conflicting binaural acoustic localisation cues for the auditory system, and as such, improve the quality of the resulting binaural rendering. Binaural stimuli are highly individual: head-related transfer function (HRTF) vary widely from one subject to another and using non-individual HRTFs leads to large perceptual differences. The physical properties of the sound scene that the binaural sound intends to reproduce have clearly an influence on perception. Assessing binaural reproduction and in particular the suitability of a set of HRTFs can be considered as a measure of degradation. In binaural synthesis, it is common to use minimum-phase HRTFs with an added delay instead of the original measured full-phase HRTFs to reduce computational complexity and to allow for variable interaural time difference values.
