If we were to add a 3rd version, like this it would always the overridden to
AIFF here, which seems not very good to me.
Also nit: wouldn't this in be more readable the other way round anyway while
solving that concern? At least I think having one-liners in the if instead of
the else part is better, though some people say you should put the less common
path in the else (though strictly speaking the else isn't even necessary with
flipped order).
if (size < 4) {
version = AIFF;
} else if (....) {
}
