Real-time binaural room modelling for augmented reality applications

“…Use of HOA necessarily increases computational demands. Optimal application of more sophisticated decoding methods is an active area of research that includes approaches designed to improve bin-aural reproduction of Ambisonic signals at both first and higher orders [18][19][20].…”

“…VBAP also permits flexible positioning of loudspeakers in which higher concentrations improve fidelity. Ambisonics, on the other hand, is generally most effective when speakers are positioned uniformly and symmetrically around the listener, using the minimum number required to reproduce the given order [18]. Vertically sparse VBAP arrays are known to present errors in elevation cue representation [22], whereas laterally situated triplets distort ITD and ILD cues toward the median plane [23].…”
