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

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,
