Precomputing the remaining floating point operations.
...tly the same environment in both cases (e.g. FIXED_POINT and with the
same mode or sequence of modes).
All that's needed is to include the code segment below in one of the .h
files and wrap all those float calculations in RECOPLAY, e.g. int sqrt2 =
RECOPLAY(sqrt(2)*16384)
I've also made RECOPLAY_MARK(name) to synchronize the process.
#ifdef RECORD
#include <stdio.h>
extern FILE *recordFile;
#define _RECOPLAY_FOPEN \
if (!recordFile && (recordFile = fopen ("precompute.c", "w")) != NULL)
{ \
fprintf (recordFile, "#include \"config.h\"...

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_fa...
