FFTs are a fairly common application of shaders (either compute shaders or fragment shaders with render-to-texture). But you’d normally use log[sub]2/sub passes for N samples. You wouldn’t try to compute a FFT in a single call because you need all of the values in each pass to be computed before starting the next pass.

I'm not familiar with OpenAL, but the way that a lot of audio libraries operate is by letting you specify a callback that will feed more audio into the output. Thus, your main program will load audio from the audio file, stuff it into a buffer (likely protected by a mutex) for the audio callback to read, compute an FFT over the audio window ...
