Echo cancellation diagnostic code
...e AEC will
automatically save the near-end, far-end and output signals to files
(aec_rec.sw aec_play.sw and aec_out.sw). These are exactly what the AEC
receives and outputs.
>From there, you'll need to start Octave and type:
echo_diagnostic('aec_rec.sw', 'aec_play.sw', 'aec_diagnostic.sw', 1024);
(the value of 1024 is the filter length and can be changed)
There will be some (possibly) useful messages printed and echo cancelled
audio will be saved to aec_diagnostic.sw . If even that output is bad
(almost no cancellation) then you probably have a recording problem.
Cheers...

Echo Cancellation Problem -- with sound sample
...ilar" to input_frame ("similar" in term of what I hear).
I have adjusted the delay between echo_frame and input_frame so that the delay is small. Below is the output from echo_diagnostic.m:
octave-2.9.13.exe:61> echo_diagnostic('aec_rec2.sw', 'aec_play2.sw', 'aec_diagnostic.sw', 1024);
Far end to near end delay is 203 samples
Delay looks OK.
Drift estimate is 0.000000% (0 samples)
A drift of a few (+-10) samples is normal.
I do not have any clue to fix this problem now. I am sitting in front of my computer for 2 days, trying out different things, but still ca...
