AUDIO SIGNAL PROCESSING DEVICE

摘要

Provided is an audio signal processing device, whereby a multiplexed audio input signal is converted by a plurality of array speakers to a playable format, comprising: a down-mix processing unit which splits the multiplexed audio signal and carries out a down-mixing of each of the plurality of audio input signals obtained thereby; a virtual sound source setting unit which treats each of the audio input signals which are down-mixed with the down-mix processing unit as signals from each of at least two virtual sound sources and applies location information to the virtual sound sources; and a wave field synthesis processing unit which generates output signals from each of the array speakers on the basis of location relations between the generated virtual sound sources and each of the speakers of the array speakers.
