The sound waves caused the needle to vibrate and to trace a wavy groove on the soft surface of the cylinder. This is kindergarten stuff, even allowing for the introduction of magnetic tape...

The sound is picked up by microphones and fed through amplifiers to a computer, which then translates the waves into a series of numbers representing the character of the wave form. These numbers are stored as binary "words."

In any case, those vibrations from...
