I would like to test the echo cancel algorithm available in unstable version
1.1.4. This echo canceller can be used with other codecs like G711?

Somebody could send me some documentation or sample, or explain the next

SpeexEchoState *speex_echo_state_init(int frame_size, int filter_length);
void speex_echo_state_destroy(SpeexEchoState *st);
void speex_echo_cancel(SpeexEchoState *st, float *ref, float *echo, float
*out, float *Y);

Thank you very much. Best regards.
