Abstract:
1. A method of processing an audio signal comprising the steps of: receiving a plurality of M sound source signals, each of said M sound source signals having an attribute including at least one of position information, movement information, and localization position information; arranging said M sound source signals in N groups so as to form N grouped sound source signals, where N is less than M; arranging said M attributes in N groups corresponding to each of said N grouped sound source signals so as to form N grouped attributes; storing the N grouped sound source signals; providing a control signal having one of position information and movement information; reading out the stored N grouped sound source signals; and performing virtual localization processing on the readout N grouped sound source signals based on the control signal and the N grouped attributes so as to produce left and right stereo signals.
