It looks like the webrtc canceller should already support multichannel operation. The webrtc canceller is the default if PulseAudio has been compiled with support for it. I suspect that your PulseAudio version doesn't have support for webrtc. Does this command fail: "pactl load-module module-echo-cancel aec_method=webrtc"? The code of the speex canceller looks like it might support multichannel operation too, if you disable all extra processing: pactl load-module module-echo-cancel channels=6 aec_method=speex aec_args="\"agc=false denoise=false echo_suppress=false\"" ("echo_suppress" is not the same thing as echo cancellation) I tried this myself, and the module at least loads. I don't know about the quality. From what I have heard, the webrtc canceller is significantly higher quality than the speex canceller, even with all the extra processing enabled.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
