Sound card problem in acoustic echo
...for the unknown reasons.
But we all know the adaptive filter of the AEC relies on the synchronization
of the far-end and near-end sampling rates.
Then Has anybody tried to use speex AEC in Windows system? How do you
solve this problem?
(I have tested speex AEC. In most computers, it has poor echo cancelltion
effect. Of course, the sound cards of these computers have different capture
and playing frequencies.)
But why MSN and Skype exhibit almost perfect echo cancelltion effect in
the same computers?
What should we do to use AEC in most computers?
(Don't tell me to change a sound card.)
