I have some opinions about echo cancelling:
1) Echo cancelling should be part of the kernel.
2) Extremely low sound latency causes the echo canceller to use more CPU!
Something in the range of 25-50ms is Ok. This is because an efficient echo
canceller process samples in blocks instead of sample by sample.
Here is the old sample by sample echo canceller that I use with ISDN
I'm currently working on a new and block based one that will be more
