Hello,

I think I will ask my question in an other way because It was not really a
success :-)

Does the AEC works in WB yet ?

In mdf.c, I can read :
 /* FIXME: Make that an init option (new API call?) */
   st->sampling_rate = 8000;

Does it mean that the AEC in WB is not fixed yet ?

Thank you for your answer, I really need to now if I have to work on that...

JC.

spx_int32_t tmp = 16000;
speex_echo_ctl(echo_state, SPEEX_ECHO_SET_SAMPLING_RATE, &tmp);

Thank you very much, I just tried speex EAC in WB with linphone and it
works great !
