...the artifacts. My processing code passes the main output of the echo canceller to the preprocessor, of course, and also the echo residuals, as the manual says. I'd assume those residuals are important for the echo suppressor, too. speex_echo_cancel( m_EchoState, &micSamples, &speakerSamples , &output, &m_Noise ); speex_preprocess( m_PreProc, &output, &m_Noise); Thanks
