<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal">I have been trying to implement speex echo cancellation algorithm on STM32F4 Discovery board; however, I could not make it work properly.<o:p></o:p></p>
<p class="MsoNormal">I tried synchronous, asynchronous way of to do that and the only thing I heard was “cazzsdaosıeoıhodg etc”
<span style="font-family:Wingdings">J</span><o:p></o:p></p>
<p class="MsoNormal">I try to use empty array for all parameters in the cancellation function, but the result is always the same (“cazzzursestosıhen etc
<span style="font-family:Wingdings">J</span>”).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What kind of problem may have hear? <o:p></o:p></p>
<p class="MsoNormal">Any help will be appreciated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
