Looking for a spectrum analyzer app or program

[Head_Unit]

I want to research the power spectrum of different music genres. So I want an app (ideally Mac but Windoze might be possible, iOS also possible)
- Play local music files (i.e. NOT just microphone)
- Ideally 1/3 or 1/6 octave, but FFT bins OK
- Ideally peak hold and average both
- Ideally data exportable. Well, really this is kind of a requirement, but if only the first criteria are satisfied I could do without this.
Any candidates? And forgiveness if I asked this before, it's been on my mind for years but I never find the right tool. I don't mind paying by the way, though I wouldn't pay too much without data export capability.

Doesn't REW have a RTA meter? I haven't seriously used the feature.
If correct you're probably asking for more in-depth analyzer which may even record the measurement throughout the length of a sample or track.
Not familiar with any but simply suggesting that REW has a lot valuable tools.

Just use Audacity.

GNU octave imports .WAV files and you can build whatever you want from there. It's a general math tool with FFTs

There is a very good Apple app AudioTools. A bit pricey and to get the best performance requires an external Mic and Apple adapter.
