Performance of the acoustic echo canceller
...ris 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 which has almost 0db echo return loss and about 20ms consistent delay. The EC can achieve about 10 to 15db echo return loss enhancement in this case. Is it normal? I would think 25+ db ERLE plus 15+ NLP/ES should...
