Hello Archie, We're having some issues getting the speex echo canceler to stay converged in a noisy, multi-path environment. We own the IPP libraries, already, so I was interested in enabling their echo canceler to see if it fares better. I see that the stubs have been put into the latest SVN to define the prototypes for IPP. Does someone have the implementation for ipp_aec_create, ipp_aec_destroy, ipp_aec_reset, and ipp_aec_cancel_echo? Were they just left out of SVN because of the upcoming release, or should I write the implementations myself?
