>>10882No there is no sound in your computer, it just stores instructions on how to actuate the linear motor that moves the speaker membrane back and forth to create pressure waves in the surrounding air. That's the sound.
Recording -> sound waves push a microphone membrane back and forth
Storing -> computer takes the signals from the microphone and translates it into a list of instructions in binary language.
replay -> computer sends instructions to speaker membrane that moves back and forth roughly the same way the sound pushed the microphone membrane.
There are more steps like signal amplification, and data compression on the instruction list, but that's just ways to make the performance better and i left that out to make the explanation simpler.
