use the camera as a reader of printed sound waves

Hello, I would like to use the camera as a sound wave reader, that is to say that the camera can interpret a sound printed on a sheet, this printed image is of the type of sound waves, that is, an image of a frequency modulated audio ( fm signal)

That is a very strange application.

Are you considering audio steganography?

I think this is an interesting project, have you found or made something more about it
