Hi Dmitry,
I met the same problem a few months ago and at that time I used 1.2beta2
code/library downloaded from Speex homepage. That bug has been fixed in the most
updated source code in svn.
Regards,
Eddy

Subject: [Speex-dev] AEC diagnistics generated files
Sorry for not being accurate in the original question.
My testing environment is set to 20ms frames (PCM 16 8 1 to be
precise).
I have verified that all the frames that I feed to the AEC have the
fixed size of 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 threads are stopped.
Any clues, guys?
Regards,
Dmitry

Hi Guys,
I am trying to incorporate the speex AEC into my RTP stack.
Trying to diagnose why the echo is not being cancelled I enabled
DUMP_ECHO_CANCEL_DATA as per the docs.
The problem is that the dump files the AEC generates are of different
size.
As I understand this and looking at echo_diagnostic.m, the files are
supposed to be of same size.
Can someone give me a hint as to why this could be happening?
Additional info:
Windows WaveIn/Out API is used to work with a sound device.
The format is PCM 16 8 2
Thanks much,
Dmitry
