Hello.<br>I'm from Federal University of Rio Grande do Sul - Brazil and I'm trying to <span lang="en"><span style="color: rgb(0, 0, 0);" title="">adapt speex_echo.h (speex-1.2beta3-win32)</span></span> to our video-conference software code. <br>
We are working on amplitude values, but I realised that in order to AEC
works, one has to convert amplitude to frequency and filter the echo
frequencies. So, my question is:<br><br>Do I have to manually convert
amplitude samples to frequency samples or is it enough to send amplitude
parameters to speex_echo.h functions that this functions automatically
convert it and do the AEC?<br>
<br>Thanks for your attention.<br> <br>-- <br>Alexandre Bento Leal <br>
