Echo cancellation problem
...mind by reminding the topic below.
Can the reason of failing be that Codec,which plays sound, and Mic are connected the different clock source?
If it is because of that, what can I do to cancel the echo? Isn't there any solution for this? Is asynchronus speex functions for this?
Best Regards,

Speex_echo_cancellation() always same output
Hi all,
I have been trying to impelement echo cancellation on STM32F4 Discovery board (having ARM based uC).In my project, I simply initialized the echo_state by speex_echo_state_init() by using frame_size 160, filter_length 800 (at 8kHz Sampling rate.) Then, I simply used speex_echo_cancellation() function in where i am getting sound. However, I have recently realised that output_frame has been
