Hot to 'scroll' through FFT

[DavidIMurray]

Hi

I am reading a binary file into LV which I contains pressure values gathered from a microphone. The data is then built into a waveform and passed to the SVT scaling Vi. From there the data is passed to a sound level vi and into a graph.

What I would now like to do is create a vi to open the data, and then display an FFT that can be moved around to give the frequency spectrum at any point in time during the recording. Any ideas how I could do this?

Cheers

Dave

Does the attached 'sample' get you somewhat nearer the solution.

There is no doubt that the sample needs to be 'adjusted' to suit your needs.
