Enscribe creates digital audio watermark images from photographic images. These images can only be seen using a third party frequency vs time display, such as Baudline (audio/baudline). Images are still visible even after such audio mangling techniques as MP3/Ogg compression, reverb, chorus, etc. Heavy EQ and flange can stripe out vertical sections, but they can also ruin an otherwise good song as well.
