SPAN is awesome. It has all that you can desire from a spectrum analyzer. All the info, all the analysis, everything you need to have all the data of your song. Put it at last of your master channel and see in real time how your mix/master is going. and it's free.
I use version 3.1 with Logic Pro X 10.4.2 on High Sierra. Never had a problem/crash.

Introduction
*******************
Best free frequency spectrum, volume and phase correlation analyzer out there! It should be an 11 out of 10!!! AND free!!!!.
Features
*******************
-) Real-time FFT spectrum analyzer
-) Volume meter
-) Phase correlation meter
-) Edit: Fourier block size, FFT window overlap percentage, visual slope, smoothness, and many more
-) Colors can be changed
-) Route different channels in one analyzer and compare them
-) K-Level metering
-) SCalable GUI
-) Statistics
-) Band-pass filter to listen to the frequency you're pointing at
-) Zoom in
-) Shows note as semitone and cent (not many analyzer do that)
-) more more more...
-) Freakin' free!!.
GUI & Usability
*******************
GUI is ok and includes different color schemes. The behavior of the analyzers can be adjusted to the situation and taste. And you can scale its x and y axis as you wish, make it double huge or just small, or everything in between. Almost no paid (and some for a lot of money) analyzer can do that. But Voxengo nailed it for free!!.
It's easy to use and self-explanatory. If it should be too difficult for you, delete the .component, no money lost because it's free!!.
Presets
*******************
It already includes very useful presets, for all different kind of situations. Albeit it's free!!.
Stability
*******************
It runs, and runs, and runs... for free!!.
Cons
*******************
I'd love to have the volume meter alone, but hey no complains here it's free!!.
Conclusion
*******************
If you don't have Voxengo SPAN, you definitely must get it right now. Because it's darn good and costs nothing, yes it's free!!.

It is brilliant for several reasons:
1. It is free
2. It has a scalable GUI and goes quite big
3. It has a high level of zoom incase you really need to know if was 53hz or 57hz you were looking at!
4. It has a band-pass filter so you can hear the frequency band you are looking at (ctrl-click on PC)
5. You can have two curves on the same page (and it is free)
6. You can change the accuaracy speed etc. in more ways than many commercial plugs (it is based on the analyser in gliss eq)
7. It shows frequency and note information for wherever on the graph your mouse hovers (and it is free)
It is free and fully featured - it simply blows other free analysers away and is much more useful than many commercial or bundled analysers available today.
I can't believe it's free! Free!
If you haven't got it, why not get it now? If you only have version 1 get version 2 now it is sooo much better!Read more

I love Voxengo's plug-ins, as soon as I got this one, it replaced my Ableton Live spectral analyzer.
Their GUI's are fantastic & with a spectral analyzer that can make a big difference. Doesn't seem to strain the CPU at all either.
Two thumbs up.
It's great to see that free products are being updated, too.
Great to have you, Voxengo. :)
This is THE meter I use on every channel. Thanks Voxengo for such a great plugin... for free :D.
No EBU R128 / LUFS metering?
