I would be quite happy to recode it to allow input and output.
Having synchronised in and out audio will be essential if we ever want
to support accoustic echo cancellation. I have been reading up on some
algorithms, it's quite complicated though and there is no algorithm
coded up (for free) that I can see. It's something of a special case of
the room correction stuff that I use in my hifi setup though.
Will take a look as I get a chance
