You absolutely can. The FFT is one cycle of a Discrete Fourier Transform, and since this data is both discrete and in regular intervals, it should behave identical to just sampling an audio signal.

I am curious why you say "The FFT is one cycle of a DFT", since the FFT is quite literally a DFT, only an algorithm in a better complexity class.
