[Discuss-gnuradio] Does the GRC FFT block re-order its output

[Marcus D. Leech]

Does the GRC output block re-order output?   I'm puzzled with respect to
what I'm seeing.

My normal expectation is that, given an FFT buffer of size N, that on output

buf[0] to buf[N/2] = DC to nyquist
buf[N/2] to buf[N] = -nyquist to DC

But that isn't what I'm seeing in GRC FFT output.   Clues?
