               Application No. 09/643,130                                                                                             


               that corresponds with the image displayed in the touched field to be emitted by the                                    
               speaker means.                                                                                                         


                       Gibson's invention relates generally to the art of mixing audio source signals to                              
               create a final sound product, and more specifically, to a method and apparatus for                                     
               utilizing visual images of sounds to control and mix the source signals, including any                                 
               sound effects added thereto, to achieve a desired sound product.  According to                                         
               Gibson's invention, each audio signal is digitized and then transformed into a                                         
               predefined visual image. Selected audio characteristics of the audio signal, such as                                   
               frequency, amplitude, time and spatial placement, are correlated to selected visual                                    
               characteristics of the visual image, such as size, location, texture, density and color,                               
               and dynamic changes or adjustment to any one of these parameters causes a                                              
               corresponding change in the correlated parameter.                                                                      


                       As shown in Figure 2 of Gibson, a microcomputer system 50 is added to a                                        
               mixing system 10 (shown in Figure 1).  The microcomputer system 50 includes a                                          
               central processing unit (CPU) 52, a digital signal processing unit (DSP) 54, and an                                    
               analog-to-digital converter (A/D) 56.  Sound signals are intercepted at the inputs to the                              
               mixing console 10, then digitized, if necessary, by A/D unit 56.  The output of the A/D                                
               unit 56 is then fed to the DSP unit 54 which transforms each digitized sound signal into
