[Speex-dev] Echo canceller: residue value

Hi Jean-Marc,
For the residue in the echo_cancel function I pass in a pointer to an array of floats. First I used an array the size of the framesize, but I discovered this causes crashes because the echo_cancel funtion writes framesize+1 floats to the pointer.
I find this plus one strange, since almost all things are exactly the framesize. Is this an error in the echo_cancel function or simply an exception?
Maybe you should define in the manual what exactly the residue is, meaning a float array of which size?
Greetings Jeroen de Kleijn
