Enscribe creates digital audio watermark images. The rasterlines of an
image are converted into frequency components via an inverse fast fourier
transform. The watermarks sound like soft hissing, but when viewed in a
frequency-versus-time display, the image is clearly visible.  Manipulation of
the audio file, such as by MP3/Ogg compression, reverb, or flange, muddies
the image, but it remains visible.
