Hello adamh,

If would like some example code for these functions you can open up LabVIEW and go to Help»Find Examples... and then search for FFT, STFT, and Wavelet. You should be able to find examples that way; however, here are three links to the functions that perform these options, and each have a link at the top entitled "examples" that you can click.

I hope this helps.
