AUDIO SIGNAL PROCESSING DEVICE AND AUDIO SIGNAL PROCESSING METHOD

摘要

An audio signal is divided into a plurality of frequency bands and a speaker unit pair is allocated for each of the frequency bands so as to constitute a multi-way speaker system. An audio signal processing device realizes a 3D acoustic effect by outputting the audio signal which has been subjected to band division to the multi-way speaker system. The audio signal processing device includes: a storage unit (8) which stores a cross over frequency which divides the frequency band while correlating it to a listening position; an operation unit (10) which receives an input of the listening position; audio signal processing units (3, 7) which perform audio signal processing in accordance with a crossover frequency stored in the storage unit (8) while being correlated with the listening position inputted by the operation unit (10).
