[Speex-dev] Echo canceller: residue value

[Jean-Marc Valin]

That's because the power spectrum includes both the DC and Nyquist
frequency. Now that you mention it, I might as well not include the DC
since the preprocessor gets rid of it anyway.

> 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.
