This sonification was originally written for the Truro Movements EP, online at http://trur.org/movements
mapudio is written in python using the numm numerical arts suite, which can be installed from http://numm.org/numm/
There are two python scripts, hearmap.py, an interactive image-player, and rendermap.py, a subscript that renders to wav files.
% python hearmap.py /path/to/image1.jpg [/path/to/image2.jpg [...]]
Controls: * left mouse button: set min_freq (x) and max_freq (y) * right mouse button: set speed (x) and num sine waves (y) * spacebar: advance to next image
% python rendermap.py /path/to/image.tif out.wav
