echo cancellation
I'm going to test the echo cancellation...
but before doing something wrong, i want to know what is the right way
to use it...

The best I can suggest is to *not* use it... unless you know how to
debug/tune it.

Residual Echo Suppression by the Preprocessor
...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
