Re: [Sc-devel] Added machine-listening UGens: SpecCentroid, SpecFlatness, SpecPcile

Josh,

Thanks for the report. Are you getting the blip sound playing back
correctly? Is the FFT buffer definitely allocated correctly? Are you
on PPC or Intel?

If you have time it'd be helpful to know if you get the correctly
resynthesised Blip, by outputting IFFT(chain).
