Sound Mural is a picture-to-sound converter. A PBM/PGM/PPM file is read on stdin and a WAV file is written on stdout. The image is treated as a spectrogram. Examples can be seen and heard on the Sound Mural Web page.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
A compile-time option was added for using a linear
frequency scaling instead of logarithmic frequency
scaling. Logarithmic scaling is still the default.
Logarithmic scaling is more musical. Linear
scaling makes it easy to do image->sound->image
conversion, as seen with Lena on the Sound Mural
Web page.
