Default Why are capstan wheels different size?

I can't think of a single method of 'reproducing sound' that doesn't
involve mechanical means.

Sound is a mechanical phenomenon. Humans use flapping meat.

I can imagine a method that used heat to move the air, perhaps with a
plasma to make it fast. (Like a modulated lightning flash.) But I cannot
be bothered to construct a search to find out if it has been done
successfully...
