Abstract

In views of a disadvantage that in a conventional method for localization of sound image in stereo listening, the amount of software is increased and the scale of hardware is enlarged, this invention has been achieved to solve such a problem and intends to provide a processing method for audio signal to be inputted from an appropriate sound source capable of higher precision localization of sound image than the conventional method. When a sound generated from an appropriate sound source SS is processed as an audio signal in the order of inputs on time series, the inputted audio signal is transformed into audio signals for the left and right ears of a person and further each of the audio signals is divided to at least two frequency bands. Then, the divided audio signal of each band is subjected to a processing for controlling an element for a feeling of the direction of a sound source SS and an element for a feeling of the distance up to that sound source, which are appealed to person's auditory sense and outputting the processed audio signal.
