[QUOTE="Mark DeArman, post: 56100, member: 950"] Re: Dual Channel FFT Okay so when using music as the source, or performing some type of differential analysis like, what is the transfer function between point A and point B. I understand those applications. Lets say I am generating pink noise from my laptop, and trying to measure the transfer function of a speaker, what is the advantage of the loop-back cable then? Why don't I just measure the the transfer function from the actual output I'm using direct to the input I'm actually using? Then use that to correct for any timing, AA filtering, other problems. I already have the data for the pink noise being generated inside the computer. [/QUOTE]
