US 2003/0152236 A1 · Audio signal adjusting apparatus

Abstract

Herein disclosed is an audio signal adjusting apparatus for respectively adjusting a plurality of raw audio signals to produce a plurality of adjusted audio signals, comprising: audio signal adjusting means for respectively adjusting said raw audio signals to produce said adjusted audio signals, and to be operably connected with a plurality of loudspeakers for respectively producing a plurality of audio sounds in a specific sound space, said audio sounds being respectively indicative of said adjusted audio signals, and collectively originated from at least one imaginary sound source having a width, said imaginary sound source being imagined to produce said audio sounds at a location spaced apart from each of said loudspeakers; location control signal producing means for producing a location control signal indicative of said location of said imaginary sound source; controlling means for controlling said audio signal adjusting means to allow each of said raw audio signals to be adjusted by said audio signal adjusting means in response to said location control signal, pointer image producing means for producing a pointer image indicative of said location of said imaginary sound source; and superimposing means to be operably connected with video signal producing means for producing a video signal having a screen image having a portion in association with said location of said imaginary sound source, designed to superimpose said pointer image on said portion of said screen image after receiving said video signal from said video signal producing means in response to said location control signal, and to be operably connected with display means having a screen to display said screen image on said screen.

An audio signal adjusting apparatus for respectively adjusting a plurality of raw audio signals each having a raw signal level to produce a plurality of adjusted audio signals each having an adjusted signal level, comprising:

audio signal adjusting means for respectively adjusting said raw audio signals to produce said adjusted audio signals, and to be operably connected with a plurality of loudspeakers for respectively producing a plurality of audio sounds in a specific sound space, said audio sounds being respectively indicative of said adjusted audio signals, and collectively originated from at least one imaginary sound source having a width, said imaginary sound source being imagined to produce said audio sounds at a location spaced apart from each of said loudspeakers;
location control signal producing means for producing a location control signal indicative of said location of said imaginary sound source;
controlling means for controlling said audio signal adjusting means to allow each of said raw audio signals to be adjusted by said audio signal adjusting means in response to said location control signal produced by said location control signal producing means;
pointer image producing means for producing a pointer image indicative of said location of said imaginary sound source;
and superimposing means to be operably connected with video signal producing means for producing a video signal having a screen image having a portion in association with said location of said imaginary sound source, designed to superimpose said pointer image produced by said pointer image producing means on said portion of said screen image after receiving said video signal from said video signal producing means in response to said location control signal produced by said location control signal producing means, and to be operably connected with display means having a screen to display said screen image on said screen after receiving said video signal from said superimposing means.
