What can more realistic possibly mean? I'm reminded of a post
I saw a long time ago suggesting that you hand your spouse or
kid or the mailman a microphone and have him talk in it and see
how it sounds.
It's going to be flat, slightly high pitched and have no echo,
reverb or other 'realisms' in it at all.
I think people (maybe specially the readers here: see threads
on AM radio) have become conditioned to hear things the way
they do on media rather than real life.
So trying to put realism back into something is going to
be totally subjective and a waste of time unless it is an
excersize in individual 'remix' or creativity.
