How does it work?A picture is actually processed as a big frequency / time grid. Each line of the picture is an oscillator, and the taller the picture is, the higher the frequency resolution is. While the vertical position of a pixel determines its frequency, its horizontal position corresponds to its time offset.
By default, the color of a pixel is used to determine its pan, the red and green components controlling the amplitude of the left and right channels respectively (the brighter the color, the louder the sound), and the blue component is not used. The action of each component can be modified in the Routing section of the Audio Settings window. Starting with version 2.0, AudioPaint can also convert the color components into HSB values, and use hue, saturation and brightness instead of red, green and blue.
