sound waveform ->FFT

[6606123]

      I get the sound file waveform,i want to have FFT transform and show on the waveformgraph,so how to do it (the labview have some control node?)and how to set waveform graph`s x-axis and y-axis.and what x-axis and y-axis means ?

somebady could help me ?

Hi!
If you have the full development edition of Labview, in the function palette => Signal processing => Transforms, you have everything needed to perform an FFT. The FFT.vi is polymorphic so it'll its inputs to your sound waveform.
Then the sound waveform can be easily read with the VI Read which is the function palette => programming => sounds => files.

I hope this help !
