Title:
AUDIO SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/135366
Kind Code:
A1
Abstract:
Disclosed are an audio signal processing method and apparatus, wherein same relate to the field of signal processing, and solve the problem of how to adjust an output signal according to a rotation change of the head of a listener or/and a movement change of the position of the listener, so as to improve the hearing effect of the listener. The specific solution is: acquiring a current position relationship between a sound source at the current moment and a listener; determining a current audio rendering function according to the current position relationship; if the current position relationship is different from a stored preceding position relationship, adjusting an initial gain of the current audio rendering function according to the current position relationship and the preceding position relationship so as to obtain the adjusted gain of the current audio rendering function; determining an adjusted audio rendering function according to the current audio rendering function and the adjusted gain; and determining a current output signal according to a current input signal and the adjusted audio rendering function. The embodiments of the present application are used for the process of audio signal processing.
