ACOUSTIC IMAGE DIRECTION SENSE PROCESSING METHOD AND DEVICE

摘要

Provided are an acoustic image direction sense processing method and device: acquiring a left-ear channel signal, a right-ear channel signal and a mid-channel signal of an acoustic source, wherein the mid-channel is located on a mid-vertical plane between the left-ear channel and the right-ear channel; according to the left-ear channel signal, the right-ear channel signal and the mid-channel signal, determining whether the direction of the acoustic source is a front direction, wherein the front direction is a direction to which the mid-channel is faced; and when the direction of the acoustic source is the front direction, respectively performing on the left-ear channel signal and the right-ear channel signal at least one of the following processings: front direction enhancement processing and rear direction weakening processing. Thus a difference between a front direction sense and a rear direction sense is increased, so as to improve the accuracy of judging an acoustic source orientation.
