I would like to have some more information about the parameter of
I have a clear idea of the importance of the filter_length in the echo
cancellation, what it is more obscure for me is the role of frame_size and
how its value affect the algorithm.
Let use, for example, frame_size = 400, would I obtain the same result of
using frame_size = 200 but with half method call?
Is it this value important for obtaining a smaller time to let the filter
adapt? or filter adapting depends only on the ratio

I will be grateful for every more info that you can give me in order to
understand better the role of frame_size algorithm.
