摘要:
A sound field controller of the invention reproduces a sound field which provides a distance perspective depending on a position of a sound image for a listener. The sound field controller includes: an A/D converter; a signal processing section for processing the digital signal using predetermined parameters, and generating a sound signal; an input device for inputting conditions which include a position of a sound image to be localized and a distance from a listener; a parameter controller for setting the parameters in the signal processing section so that the sound signal has characteristics in accordance with the input conditions; a D/A converter; and a reproducing unit for amplifying and reproducing the signal output from the D/A converter.
