opus - Nov 2017 - Fixed point modules in floating point

Hi,

I was testing floating point  Opus encoder. But it's calling few functions
which are implemented in fixed point . I tried to find corresponding
floating point functions in source. But not available. Please help me on
this.

The same code does both fixed-point and floating-point. If you define
FIXED_POINT, then the macros and types operate on fixed-point.
Otherwise, they all map to floating-point.

Thanks for info.

I just  rename Makefile.unix to Makefile without running configfile to
generate Makefile.


By default , FIXEDPOINT macro  disabled .
For fixed point , I just enable FIXED POINT macro in the given makefile.

For both cases , encoder using VAD.c which is implemented in fixed point
and multiplication macros defined in macro.h .

While debugging I came to know  I that All operations are in fixed point .
Nothing is mapped to floating point when FIXEDPOINT macro disabled.

All variables are also mapped to Opus int for both cases.

Do I need to enable or disable any other parameters to run VAD in floating
mode ?

Please let's me know

Thanks
