Stereophonic sound reproduction system

A stereophonic sound production system comprising:

• at least two audio signal outputting devices which output audio signals in the form of sound to create virtual sound sources at desired locations in a three-dimensional space around a listener, thereby developing a three-dimensional sound field, the virtual sound sources including a direct sound source which produce a direct sound heard directly by the listener and Nth order reflected sound sources which produce Nth order reflected sounds resulting from reflection of the direct sound where N is an integer more than or equal to one;
• a direct sound source localizing circuit which produces audio signals to localize the direct sound source to the desired location in the three-dimensional space;
• a reflected sound source localizing circuit which produces audio signals to localize the Nth order reflected sound sources of the same order to the desired locations, as specified around a source-to-listener line extending from the direct sound source to the listener;
• and
• an audio signal combining circuit which combines the audio signals, as produced by the direct sound source localizing circuit and the reflected sound source localizing circuit, to produce the audio signals to be outputted from the audio signal outputting device respectively.
