Android Question How to stuff a wav file into the FFT library

[Rattigan_Roger]

Hello
I want to use the FFT library with a wav file to do an analysis to determine the frequency.
Can anyone shed some light on this?

Thanx in advance for any clues ...

Thank You ever so much
I'm still out in weeds but I now think I can actually see where I'm going.
