[hpsdr] FFT latency

[G3XJP]

Jay, this is the bit I don't get.  I think maybe this concern is what 
prompted me to ask the original question.   If the delay in an FFT is 
unavoidable and inherent, how does throwing more, better or dedicated 
hardware at it help in any way?   I can see how it would help release 
resources so you don't add to that inevitable delay.  cheers, Peter G3XJP
