An Orthogonal Frequency Division Multiplexing fax machine!
A good way to send encrypted pictures. Just convert the images into audio, and nobody would even think to look at the spectrogram of the audio file. Nice.
Better than playing a record backwards to find the hidden messages. Instead you can find hidden images in recordings.
Very interesting!
