ImageTuner is a Java project I created to work alongside ARSS, a program by Michel Rouzic.
ARSS converts an image into sound, by reading each row of pixels as a specific range of frequencies. ImageTuner provides methods for creating more harmonic sounds, by first manipulating the source image to emphasize frequencies tuned to a given scale or chord.
ImageTuner is one of the main tools in my automusika project.
I created ImageTuner mostly as a tool for my own experiments with image resynthesis, and it seemed a bit specific to release publicly. Someday I may polish it up and document it for release. Until then, you can contact me if you are interested in using it.
