Trouble is sound is essentially a one dimensional time
waveform, whereas a monochrome image is two dimensional
spatial distribution.

One solution might be to use stereo sound. Now you can get
your X axis information in terms of spatial position. Your
Y information could be encoded as frequency, so that up is
a higher note, down is a lower note, and finally intensity
could be simply encoded as loudness.

I guess if you had a very simple picture the sound version
of the chief blob might be meaningful. But what listening
to the Mona Lisa would sound like - I know not.

I've always been led to believe that you can get 1000 words
from a picture. Don't know how though.

I know how to do it. But let me why do you want the technique, I mean where will you apply it?

i know how to do it also! a fax machine, or amateur radio
slow scan television software... either one will rasterize
and convert your image to sound.

I imagine LSD could help you turn images into sound, and
probably sound into color and color into the heartbeat of
creation.

Hi
It seems that peaple are puzzeled by what you are trying to
do. I am not. I know someone who have tried to recreate the
sound of the big bang. You may try the following
1- save your image in "work" with known name and format for
example mypicture epg
2- z=imread('mypicture.epg);
z=double(z);
3=f=1000 %for example
y=sin(f*z);
sound(z)
4- see what you get and change f accordingly
