The acoustic processor, vis-a-vis acoustic image normal position processing method and the acoustic image normal position

摘要

PROBLEM TO BE SOLVED: To stably obtain vertical sound image localization effect over a wide frequency range without performing complicated processing.;SOLUTION: In a sound processing apparatus, a sound image localization processing filter 12 provides a sound signal with a characteristic according to a difference between a previously measured first head-related acoustic transfer function (upper HRTF) of a sound generated from a virtual sound image position 20 to an ear of a listener and a previously measured second head-related acoustic transfer function (lower HRTF) of a sound generated from a speaker 13 to the ear, and localizes a sound image upward or downward with the sound generated by the speaker 13.;COPYRIGHT: (C)2011,JPO&INPIT
