Abstract
A method and apparatus for mixing audio signals. Each audio signal is digitized and then transformed into a predefined visual image, which is displayed in a three-dimensional space. Audio effects added to the audio signals are transformed into predefined visual effects images, which are also displayed in a three-dimensional space. 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. Dynamic changes or adjustment to any one of these parameters, or parameters of the audio effect images, causes a corresponding change in the correlated parameter or audio effect.
