...to do > here. If you find anything, I'm definitely interested. The one idea I have is to have a default gain2 of 0dB and only when the residual echo goes high we reduce the gain2. This could be implemented similar to eq. (3) and (4) in this paper: http://research.microsoft.com/pubs/69504/diegobenderskyhdres.pdf The idea would be to use your estimation of the residual echo and noise But to modify the calculation of the gain2. This would probably offer a more robust solution since we do not have to rely on the SNR. However we would lose the noise suppression functionality I guess (which probably i...

My impression is that it does not make much difference on the timing to set this parameter less aggressive. Depending on the how loud the near end is talking it may detect double talk but most
