enscribe [options] [input image] [output sound]
enscribe converts the scan-lines of the input image into frequency components and then using an inverse Fast Fourier Transform, converts them into sound. The left side of the image is the low frequency end, and the right is the high end, up to just under the Nyquist limit if you want it to. There are several tunable parameters as to how colour is converted into stereo sound and the frequency range to be used. This conversion can be used to create resilient audio watermarks or to simply create interesting sounds from images.
This manual page should be expanded to contain descriptions of the command-line options.
