Re: FFT on microphone signal

Your VI doesn't show how you are trying to use FFTpt by pt. 

 

Why are you using FFT pt by pt?  Why wouldn't you use the regular FFT function that takes in the whole array or waveform at once?

 

An FFT doesn't help you display a waveform without noise.  An FFT is the mathematical analysis of all the component frequencies that make up the waveform.
