...my recording file for that live call. Basically I don't see the difference between input_frame and output_frame. As I mentioned in my original post, the echo return loss is about 20db. I guess the echo cancelleris not really actively cancelling the echo in such condition? But without the echo sppression/NLP, echo is still noticable. I used the same onboard sound card for the speaker and microphone. As far as I can tell, the delay between echo_frame and input_frame is consistent and about 10ms. I would assumethe synchronization is not a problem. And I also have some other echo recording files w...
