All I want to do is write a spectrum analyzer module for MAME to show a spectrograph of the VGM player driver. Why is it so hard to find a bloody Discrete Fourier Transform algorithm in C or C++ that just does what it says on the tin and doesn't have external dependencies?!

As I understand it, FFT will work for arbitrary sizes as long as I pad out the sample count to a power of two. I'm assuming for unsigned audio data, the best choice would be to pad with zeroes.
If you can point me at a link to the repo for REAPER, I'd be happy to take a look. Thanks for the advice already!

I've already got a one-liner for a straightforward Hann window, but if you have a suggestion for a better windowing algorithm for a bar-chart style spectrograph, I'm all ears!

Hann is fine, anything but rectangular is probably plenty. :)
