FFT filter smoothing

I'm working on the second derivative analysis of IR data. The signal to noise loses are currently such that my second derivatives are noise mush (even after smoothing). In working with a colleague, he suggested using a FFT filter smoothing. Is there a build in function in Igor similar to FFT filter smoothing in Origin?
I don't know if it is the same as Origin, but the Analysis menu of recent Igors (version 6 or later) has a Filter... menu item that may do what you want.

Thanks Jim. I'll see what I can do with this because I strongly dislike origin...
Hello ablakeley,

Take also a look at the Discrete Wavelets Transform (operation DWT [/D for denoising] [/S for smoothing]) (cf p.1286/1994 in the manual)
Take your time to analyze the syntax, then test with different parameters (thresholds, kind of wavelets...), make sure to specify the /P flag.
Type your command in the command window, and you should be able to get a clean signal.

Best Regards
