	I rewritten my program so it is more similar to yours, I grabbed your code 
	for storing and retrieving echo, and I have better results, I think the 
	echo is cancelled in about 50% but it still can be heared. I think there 
	is a problem with jitters on windows. on linux you have smaller latency 
	then on windows. does anyone ever managed to succefully use echo 
	cancellation from speex in windows enviroment? I know it's possible using 
	high-end sound cards with native ASIO drivers. But what about ac'97 
	on-board chips?
