Yes - it should be integral. And I can get rid of the buzz on this
particular test by adding:
for (i = 0; i < AMR_SUBFRAME_SIZE; i++)
exc_feedback[i] = truncf(exc_feedback[i]);
But since the decoder is not bit-exact, how can I know that this has
solved the problem? I'd need a bound on the size of the error between
this decoder and the reference.
