...nceller finds a correlation in 4-5 timebins instead of just one. We could reproduce the same result by playing a human voice saying "aaaaaaaaaa" without variation in pitch; the weights for those frequency bins would increase for all the timeslots in W. Now, people don't say "aaaaaaaaaaaaa" all that often, but they do play music that has a few "long" sounds, and saying "aaaaanyway" is enough to trigger this. Next test, what happens if the user has an external (physical) on-off switch? Same setup, playing Big Gun as loud as it gets. Apart from the proble...

Good afternoon... Currently my Unix and Windows UID's don't match, nowhere close to it. I use AD for the Windows side of the house from a Win2K8 Server and I still use NIS for the Unix/Linux side of the house. I don't do single sign-on yet, so everyone in the building has a Windows account and a Unix account with two different UID's, but the same username. Now, I'm at a

Hi, I'm still working on visualizing the echo canceller, but I discovered something that might be interresting. During testing, i did this: Generate a test signal (10+x sine waves per frame), where x increases by one for each iteration, and wraps around at 100. Set the speaker signal for the frame to the test signal. Add 0.5*test signal to the mic signal. When watching the power graph

...obably making it harder than > for a real scenario because any movement causes the echo path to change. Actually, with maximum volume (which I used to make sure the echo really dominated over the noise), it's quite loud, so I left it in the corner. >> Now, people don't say "aaaaaaaaaaaaa" all that often, but they do play >> music that has a few "long" sounds, and saying "aaaaanyway" is enough to >> trigger this. > > Can you sent a pair of files so I can run testecho on?
