and what is sound, electromagnetically transmitted, then turned into
ones and zeroes.
Just to be picky sound is mechanical waves not electromagnetic.
The ear is primarily a mechanical device.
I meant after your voice speaks(sound waves to em), and before it
vibrates the speaker(em to sound).
You're skipping a few steps, but unless you're using a cordless radio
microphone, there's no em between your voice and the speaker.
Radio waves, as well as light, are electromagnetic. Sound is very
different, and so is the electrical signal produced by a microphone.
In any case, none of your responses corresponded to the OP's query.
