hi all, i am using the echo canceller feature of Speex 1.1.10. But still i m able to hear the echo. i have used 360 frame size n the filter lenght 100*frame size. So i called the functions as below : speex_echo_state_init(360,100*360); speex_preprocess_state_init(360, 8000); and then i hav called the echo cancel and preprocess functions. But still there is echo. How can i remove that ?? thanks 4 the help, Sonpoopre --------------------------------- Enjoy this Diwali with Y!
