I don't know of an existing project that's public, but an M3 should be
powerful enough to run the CELT modes of libopus without much
difficulty, as long as you have one running at a sufficiently high clock
rate (I think the STM32F103, for example, goes up to at least 72 MHz,
which should be plenty). You may have to do some work to get all of
libopus to fit in the limited Flash+RAM available, though.
