...make these problems 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 w...

...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 threads are sto...

...wever it would be good to have more stages displayed during processing action. It's also not clear why echo_diagnostic function freeze sometimes and after applying Ctrl+C and restarting it again, working fine. final question is, if it's possible to use regular .sw files for aec_rec.sw and aec_play.sw parameters instead of special hardcoded filenames. If yes, what is necessary to do in order to be able to support such files? I'm sending my version of echo_diagnostic.m with more printfs added (some of them may not exactly match activity, so please correct me). thanks -------------- next...
