Well, it shouldn't be too difficult for lateral-cut monophonic
records, since the path of the cut groove defines the waveform
which will be reproduced. Vertical-cut records would be more
complicated to read from image, since the modulation appears
as groove depth rather than groove path...and stereo records
carry both lateral and vertical information, thus presenting
a challenge!
