[Speex-dev] Echo cancelling results

I wanted to play around with the echo canceller so I tried the testecho
As speaker sound I fed it with a 440 Hz sine wave, and as mic with a 550
Hz + 440 Hz sine waves sound (but the 440 Hz component half the amplitude).
I kind of expected to get a somewhat clean 550 Hz sine out, but it
doesn't seem to work that way.
Are there better samples I can use with testecho to see some results
from the echo canceller?
Or did I do something wrong?
