[Speex-dev] Echo cancelling results

[Magnus Ekhall]

Hi,

I wanted to play around with the echo canceller so I tried the testecho 
program.

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?

Thanks,
Magnus
