Abstract
A sound image localization device which includes a signal source for outputting an audio signal, a signal divider for dividing the audio signal output from the signal source into two digital audio signals respectively for two channels, and a first signal processor for receiving one of the two digital signals and processing the digital signal so as to localize a virtual sound image using a filter having a first frequency characteristic. In addition, the sound image localization device includes a first D/A converter for converting the digital signal output from the first signal processor into an analog signal, a second D/A converter for receiving the other digital signal obtained from the signal divider and converting the signal into an analog signal, a first control speaker for outputting the audio signal obtained by the first D/A converter to a prescribed space area; and a second control speaker for outputting the audio signal obtained by the second D/A converter to a prescribed space area.
