I fix it. I forgot the speex_preprocess(m_pPreprocess, buf, NULL) need to do
enough samples too.
Tks a lot!
            speex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_DEREVERB,
What are these source code mean? I can not find any document about them.

I'd say check the result just after denoising (try without denoising
too). Also make sure you've got the right number of samples and all. I
can't say much with the info you're giving me.
