[Speex-dev] Problem in Echocancelation

[boby_suresh at yahoo.com]

hi,
 I tried that . we did the same as in the source. but we lost voice also no voice is coming after the echo cancellation some noise is coming.  here I am sending code we used.

echo_state = speex_echo_state_init(20, 100); - to get echo state.
speex_preprocess_ctl(preprocess_state,SPEEX_PREPROCESS_SET_ECHO_STATE,echo_state);

To cancel echo
speex_echo_cancellation(echo_state, (spx_int16_t*)input, (spx_int16_t*)&FramePlayed, (spx_int16_t*)&EchoCancelledFrame);

then we encode it using
speex_encode_int(enc_state, (spx_int16_t*)&EchoCancelledFrame, &bits);

Without echo cancellation our code works properly. only after adding echo cancellation it gives problem. Can you give some help to get out of this problem.

Thank you
Suresh A
