Abstract
According to a sound image direction sense processing method and apparatus, a left-ear channel signal, a right-ear channel signal, and a centered channel signal that are of a sound source are obtained; whether a direction of the sound source is a front direction is determined according to the left-ear channel signal, the right-ear channel signal, and the centered channel signal; and when the direction of the sound source is the front direction, at least one type of the following processing: front direction enhancing processing or rear direction weakening processing is performed separately on the left-ear channel signal and the right-ear channel signal. Therefore, a difference between front direction sense and rear direction sense of a sound image may be enlarged, so that accuracy of determining a direction of a sound source may be improved.
