Sounds of Mars

Nasa's recording of "Sound of Mars" was converted into a giant monochrome image and then transferred into sound using a raster-based sonification system I developed. The scanning area automatically moves left and right and up and down over the image area. During this, the sonification resolution can be adjusted from 5x5 to 50x50 pixels and 5 representative colors can be selected to change the tonal character of the sound.

Each pixel has a heavily-processed electric guitar sound. The number of voices increases and the pitch and the phase relationship between each voice change according to the number and color of pixels. Also, the sonification time can be warped vertically and horizontally. This applies granular effects to the sound.
