hey
we just have a reference encoder. use another tool to convert to .au
first. i'm not sure it's worth the effort to add more formats to the
encoder when it's just for development.
to reiterate: we want the encoder to work transparently as a plugin
inside alsa. maybe i'll be able to get back to that now.
