VOSIS is a synthesizer combining audification of greyscale pixel data with several image filters. It is a tool for image sonification, visual music composition, and experimental sound design. The audification of pixel luminance values creates shape-timbre relationships. Pixel scan rate is controlled in terms of note interval, octave, and scale to give varying pitch between image regions. The ADSR envelope allows one to play images as a non-linear sequence of pitches with varying wavetable/timbre. For more features including presets and unlimited recording see VOSIS Pro.
