[Speex-dev] fixed point AEC

[Deepa Bhatt]

Thanks Jean, I missed that detail. 
   
  I have a few more compile errors if you could help me with it =>
   
  In function speex_echo_state_init in mdf.c I am getting error: "undefined reference to exp". I don't see a fixed point implementation of "exp". Can you point me to the correct files.
   
  I am using the following files from speex 1.2 beta1 =>
  mdf.c, math_approx.c, misc.c, fft_wrap.c, kiss_fft.c, config.h, speex_types.h, speex_echo.h, arch.h  .

There are two FFTs in Speex, one of which (kissfft) works in fixed-point
(and is enabled by default). The AEC works fine at least on Blackfin.
