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
