Thanks, Chis. I'm glad it works for you. When I get some time, next thing is to add code to handle different number of points on different curves. So, it will have to interpolate...

Very Nice. I disabled the x-axis by remming out lines 231,250,251,274. Since I normally plot using semilogx, the x axis shifting doesn't work well as is. An option for x or y only shift would be nice. A little display showing the current value of shift would be nice too. Very usefull as is though...

I also like it, BUT doesn't seem to work well when the x axis is log based. This is pretty much all I use (frequency is normally plotted this way). I looked at the code but not sure how long it would take me to make that mod.....

As an electrical / acoustics engineer I've been looking for a function like this for several years. I would have written it myself but my signal processing skills are not where they need to be. I finally stumbled across this function, and decided to try it. The octave smoothing matches very nicely with Goldline TEF smoothing, until you get down to the low frequencies (I'm talking around 100 Hz), but upon inspection it could have something to do with 1.) not enough data points down here, or 2.) something else with the algorithm. I know another company, Audio Precision, uses a proprietary smoothing algorithm to accurately smooth the lower frequencies but I'm not sure what that is.

I'm giving it five stars because it does exactly what it needs to do, which for me is smooth frequency response information. Thanks Todd!
