> I think they are actually the same thing when viewed through the lens of signal theory analog audio vs. analog video with no audio : initial form/end form of presentation/production of a transmission: Just difference of which comes first, pi/3.14 or e/2.7. a) analog/monotone audio : transformation of visual score/musical spread sheet ("euler expressions") to complex analog wave form (pi/ sinusoidal expressions). b) analog/monochrom video (no audio) : complex analog wave form (pi/sinusoidal expressions) to visual picture frames/pixelized spreadsheets ("euler expressions")
