There are provided a plurality of filter units provided in corresponding relation to a plurality of predetermined directions on a one-to-one basis, and each of the filter units processes an input tone signal with predetermined transfer characteristics peculiar to the predetermined direction corresponding thereto. Each of the filter units processes the tone signal with transfer characteristics for simulating transfer of a sound from the corresponding predetermined direction to left and right ears of a human listener, and thereby outputs processed tone signals corresponding to the left and right ears. Namely, sound image localization is achieved by synthesis of sound components arriving from a plurality of different predetermined directions. Variation of the sound image localization can be controlled by controlling respective levels of input signals to the individual filter units. Direct sound signal and reflected sound signal delayed behind the direct sound signal are input to the individual filter units after having been subjected to respective level control, so that completely-stereophonic sound image localization is accomplished by a combination of the direct sound signals and reflected sound signals.
A sound image localization apparatus for receiving an input tone signal and localizing a sound image of the tone signal in a given position, said sound image localization apparatus comprising
A sound image localization method for receiving an input tone signal and localizing a sound image of the tone signal in a given position, said sound image localization method comprising
A machine-readable storage medium containing a group of instructions to cause said machine to perform a sound image localization method for receiving an input tone signal and localizing a sound image of the tone signal in a given position, said sound image localization method comprising
