How to simulate the echo in G.167 AEC specs? - ding...@hotmail.com - Dec 6 10:24:00 2005
Hi, All
I'm currently doing a project on G.167 compliant AEC.
For teleconference systems, the reverberation time averaged over the transmission bandwidth shall be typically 400 ms;
For hands-free telephones and videophones, the reverberation time averaged over the transmission bandwidth shall be typically 500 ms;
For mobile radio telephones, a typical average “reverberation time” is 60 ms.
My question here is how to simulate the echo? Is there any software to simulate such long echo? Thanks
Kevin
