echo cancellation test problem on Windows OS.
...orea.
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.

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....

About echo CPU consuption

Jean, thanks for your source code example.

cause the sound poppling with a celeron 1.7Ghz (taskman show cpu full,
without echo is at 30%).
Does exist a mode to lower the cpu consuption in echo removing? Because a
large part of users base own still "old" CPU of 6-7 generation, as from
500-700 Mhz and lower
