PURPOSE: To give the impression that the sound comes from an area different from an actual loudspeaker to a game player by operating a monophonic signal output from an audio synthesizer corresponding to information on the sound position of a game software. CONSTITUTION: A sound processer 220 processes a monophonic signal from an audio synthesizer 180 corresponding to information on sound positioning from a game software 10. Each monophonic signal from the audio synthesizer 180 is divided into two signals, and one of them is converted into a voice signal of two channels having the phases and amplitudes different from each other in dependence on the frequency, according to a transfer function of the sound processer. Then the signal is transferred through the transfer function, and is formed as a two channels output signal having the differential phase. Thereby the amplitude relationship adjustable by the frequency, is formed therebetween. |
