Hi, I wanted to know how the speex echo canceller can be used for multiple channels audio. I am aware that support had been added for multiple speakers and multiple microphones. Is there any documentation on how speex_echo_state_init_mc can be used in conjunction with speex_channel_decorrelate?

Sorry about the current lack of documentation. You might want to have a look at http://people.xiph.org/~jm/papers/valin_hscma2008.pdf to get an idea of how things work. Cheers, Jean-Marc
