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 ?
