Filtering Peaks in an FFT

[needtolearnfast]

I am finding peaks in an FFT and want to output them. I have been able to do this alright, but the issue I run in to is if there is some noise and the peak is shifting ever so slightly, the peak is stored twice. Is there an easy way to monitor for close peaks and weed them out? Thanks.

If the first peak is at index k, then start looking for the next peak at index k+m, where m is the minimum number of frequency bins you expect between "real" peaks.
