ABSTRACT:
An audio signal adjusting apparatus for adjusting raw audio signals to produce adjusted audio signals, comprises an audio signal adjusting unit for adjusting the raw audio signals and operably connected with loudspeakers for producing audio sounds that collectively originated from an imaginary sound source. The imaginary sound source is imagined to produce the audio sounds at a location spaced apart from each of the loudspeakers. A controlling unit allows each of the raw audio signals to be adjusted in response to a location control signal indicative of the location of the imaginary sound source. A pointer image producing unit produces a pointer image indicative of the location of the imaginary sound source. A superimposing unit is designed to superimpose the pointer image on a portion of a screen image after receiving a video signal from a video signal producing unit in response to the location control signal.
