Plausibility and immersion are two of the keywords which describe quality features of virtual and augmented reality systems. There is a plethora of research results in this area, but current headphone based systems still do not enable auditory illusion for everybody and all types of signals. To address the open questions, a series of studies have been conducted to study the quality of spatial audio reproduction using binaural synthesis. This contribution gives a revisited insight in the creation of a perfect auditory illusion via headphone. First, a summary on technical parameters to realize correct auditory cues is given, which includes requirements like headphone equalization or interpolation methods. Second, we will point out that beyond reproducing the physically correct sound pressure at the ear drums, more effects play a significant role in the quality of the auditory illusion (and can be dominating in some cases and overcome physical deviation). Perceptual effects like the room divergence effect, a...
