Echo cancellation diagnostic code
...lems easier to debug. You'll need to have svn version for this.
First, you need to manually define DUMP_ECHO_CANCEL_DATA in the
compilation (sorry configure switch for now). With that, the 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 (po...

AEC diagnistics generated files
...320 bytes.
So this is why I am presuming that the the dumped files should be of
equal size.
The output signal is good and not distorted. It has echo, though.
In a try to diagnose that I have followed the documentation and set the
DUMP_ECHO_CANCEL_DATA compiler variable.
The canceller generated aec_out.sw, aec_play.sw and aec_rec.sw and they
all appear to have uneven size.
Octave complains about the files which is logical as it's trying to
multiply matrixes that have different dimensions.
I have checked that tear-downs are made correctly and
speex_echo_state_destroy() is called after the th...
