code from www.3gpp.org. The license of the code from 3gpp is unclear so you
have to download the code separately. Two versions exists: One fixed-point
and one with floats. For some reason the float-encoder is significant faster
atleast on a P4 1.5GHz (0.9s instead of 9.9s on a 30s audio clip at MR102).
Both float and fixed point is supported for amr-nb, but only float for
