Hi all, I have been trying to implement speex echo cancellation algorithm on STM32F4 Discovery board; however, I could not make it work properly. I tried synchronous, asynchronous way of to do that and the only thing I heard was "cazzsdaos?eo?hodg etc" :) I try to use empty array for all parameters in the cancellation function, but the result is always the same ("cazzzursestos?hen etc :)"). What kind of problem may have hear? Any help will be appreciated. Best Regards, Kahya G?ZL?L?K NOTU: Bu mesaj ve ekleri yaln?zca g?nderildi?i ki?i(lere) ?zeldir ve gizlidir.
