For my VoIP application machine A sends speex encoded audio of to
machine B and vice versa at. Data is captured in PCM 8Khz, 16 bit
and then encoded using speex 1.1.12

The packet A played and the packet A captured through mic are the
input to speex echo canceller. So I am trying to remove traces of
packet A played from the captured data. I have followed example

All I hear is some metallic sounds and after some time there is an
illegal memory reference in mdf.c filter_dc_notch16 function at
spx_word16_t vin = in[i]

Any clues as to what is going wrong?
