Multichannel Audio Coding Based on Minimum Audible Angles
The method described in this paper provides a scheme for encoding multichannel audio signals representing a spatial auditory scene based on human sound perception in space. It relies on a psychoacoustic model based on measures of minimum audible angles (MAA) in the presence of distracting sound sources. A compression gain is obtained by truncating the order of representation of the auditory scene in the Higher-Order Ambisonics (HOA) domain according to the psychoacoustic model. Numeric simulations were conducted in order to link the error of representation of the field with an angular distortion of the apparent direction of the sound sources.
