Hi, I'm still trying to implement speex AEC into my VOIP project and I have some problrm with MDF filter response. I have plots of ref(near-end), y(filter response) signals and from plots I obtain that filter response is to small so when i substruct it from ref signal there is no efect. Is there any way to make filter giving response about ref signal amplitude? /Przemek Stajniak.

Hi,all I have tested AEC on files, it works well.I have some files,one is echo file, others are echo-added files(an origin file adding echo at different delay,such as 20ms,40ms...120ms,140ms).AEC do wonderfully on those files except echo added at 140ms-delay. But ,when i use AEC in my voip project, it does feebly. Who can give me some hints why caused this.How long can sound be picked up by

Jean-Marc, I think I can speak for most everyone here when I say we appreciate *very much* your code beyond the codec that helps people who use Speex in real applications. How far you want to take that code is up to you, of course. (And contributors, to a degree.) I don't think any reasonable person is expecting your code to solve everything. But when people are running up against
