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
