Abstract:
1. A sound image localization apparatus for executing a sound image localizing processing on the basis of a head-related transfer function, comprising: a frequency component comparing/correcting unit operable to compare frequency components of a sound source signal with frequency components of said head-related transfer function corresponding to a position of said sound image to be localized, to determine whether or not a sound image localizing signal is distorted by a clipping distortion, and to correct said frequency components of said head-related transfer function when said sound image localizing signal is distorted by said clipping distortion; and a sound image localization processing unit operable to execute data processing by using said sound source signal and said head-related transfer function corrected by said frequency component comparing/correcting unit, to output a sound image localizing signal, wherein said frequency component comparing/correcting unit suppresses an amplitude of said head-related transfer function for each unit of peak or dip.
