Hello I try to use AGC,Denoise and other utilities of Speex lib on a conference in pj-project1.0.x. For this approach, I worked on the mix_buf of each conf_port on write_port func. I attach my source codes (conference.h, conference.c) to this email. I checked the result of my changes on conf and they work good. Please verify my changes. I am not sure that my changes are correct. Please help me. -------------- next part -------------- An HTML attachment was scrubbed...
