Hi, all.
I'm a programmer lived in Korea.
This time, I was investingating echo cancellation and found speex echo 
cancellation related API.
But echo stilll remains.

1. echo cancellation using only files works propertly.
2. echo cancellation using sound device works not propertly.

You can download test files as followed.

file )

The reason why echo still remains is that speaking signal from sound device 
differs from speaking signal from file, I guess.

It's my pleasure to see my testring files.
Thanks in advanced.
