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...

...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...
