Precomputing the remaining floating pointoperations.
Firstly, running for more channels will not break my hack. All that's needed
is to call RECOPLAY_MARK with different identifiers (say nb, wb or uwb)
before doing the appropriate initialization.
Secondly, my attempts to do the Gaussian in fixed point went like this :
Define a new constant lag_factor_gauss that is manually set equal to
exp(sqr(2*M_PI*lag_factor)/-2) by whoever changes the lag_factor. From bash
you can say
echo 'e((8*a(1)*.012)^2/-2)' |bc -l
Then we can replace the code in the init functions with :
gauss = 16384;
for (i=0;i<st->lpcSize+1;i++) {
st->...
