I have never really fully understood how a speaker vibrating air molecules which then in turn vibrate the membrane in your ear works. How can a speaker make multiple sounds at the exact same time if its based on movement of a physical object?
In: Physics
Take a music. Draw the sound wave of that music. A squiggly line up and down denoting signal amplitude and frequency.
The speaker is reproducing this line with its cone movements.
A pure analog audio solution captures that complex wave intact. The grooves in a record are analog to that sound wave. That gets played back in an analog speaker
