Can we detect the fundamental of some notes from a musical instrument with fft-real? #1

Hi, I am looking at the Qt "Spectrum example" sample project that uses FFTReal. (I am not sure which version) What I would like to do is to guess the fundamental of some music notes, played by an instrument. I want to build a tuner. Would that be possible with FFTReal? Should I use FFTReal for such a task, or would FFTW be faster? How can I achieve this? Thank you!

Hi aalex, I'm just hosting this copy of fftreal here as it made the build process of one of my projects easier. It's not my library, and I can't support it.

But, it might be what you're looking for. Here's a couple of useful/interesting links I found:

I hope that helps.
