thanks for your response. We are experiencing a loud echo on the far end side.
So far we tried various values for the ecL Filter Length and the ecFE_SpeechDelay but without any noticeable improvements.
Sometimes the echo seems to be a little bit cut off or off higher frequency. With low values for the speech delay high frequent artifacts seem to be introduced.
We also tried increasing the ecMux values with noticeable but not good results for ecMu0 > 0xC350 and ecMu1-3 increased as well. With these values the echo becomes heavily distorted but not reduced.
Do you have a best practice/Guideline for which values to increase/reduce to mitigate the echo?
Something like: if the echo sounds more high frequent, try increasing value xyz in steps of 5 until... Then start manipulating value abc ...
