Reading in HZ

[blb5h7]

I have a project where we want to read the frequency of a golf club head upon impact with a ball using LabVIEW. We are using an Electret Microphone to obtain this data but LabVIEW spits back voltage for readings. How do I convert these voltage readings to Hertz? Attached is what I have so far for a vi. 

Your help is much appreciated!

Since this seems like homework, I will give you a hint.

You are measuring a signal in the time domain with units of seconds, but you want to know how it looks in the frequency domain, units of Hz or 1/s.

There is something that can transform, hint, hint, the signal from the time domain to the frequency domain.

cheers,

Fourier Transform

In your case, there is a simple FFT VI that you can use.
