Excellent news ! Kudos to this Chinese guy !!

Maybe we could suggest MPC to Rio for inclusion into the Karma ? MPC
wouldn't hurt, it already has Vorbis.. ;-)

Their developers seem very open-minded, so if the module is well-written
and they probably have licensed pretty much every audio format already -
it might be a good idea.

Anyway, I wouldn't do it before we all agree.

By the way, does someone here have an ARM-based development board and
some skills for testing the codec ?

Best Regards
