Spectrum Analyzer

Member Since: Dec 17, 2007

My ear is not as good as I'd like it to be. I was wondering if anyone knows of any stand alone free spectrum analyzers? Mainly to check and train my ear. I've read a few articles here about notching out frequencies to blend tracks together so nothings gets muddy or sits on top of the mix.
I'm running acid pro 4 so I can't use any vst effects. Thanks.

There's a few that I've used,

Inspector free edition,

bluecat has a free analyzer,

but I think the one I use the most now is Voxengo's Span, which is also a freebie.


edit: I liked bluecat's analyzer too, but it was a little bit of a resource hog. SPAN is lighter on the CPU usage.

Thanks for the reply. They look like they'd be perfect, but I can't run vst effects, just softsynths. Is there any kind of free program I could run these on?

Kristal Audio Engine is a free VST-capable multitracking app. You can get it from here:


Its a great entry-level multitracker, especially for a freebie.

Audacity is another one, although you have to do a little work with it to be able to use your own VST plugins (it defaults to only being able to use the supplied VSTs):


As for a free VST frequency analyzer, I like Fre(a)koscope:

I downloaded Kristal Audio Engine and tried some of those analyzers. I wish my acid 4 could run those. I will load some of my tracks in question into Kristal to use the analyzers.
Thanks for the help.

Both J-bot and Tad, thanks a million!! I've been looking for something like these for a long while now to help me learn my instruments hot spots and other various mixing techniques. Will be a huge help in my effort to learn, thanks :)

Glad to be of service. Now if I could only READ a friggin spectrum analyzer. Might as well be a rectum analyzer for all I know.

I mean, I understand the frequency spectrum, but I never see any frequency jump out as dominant when analyzed. And how do I tell if there's too much of any 1 frequency? Or too little? The logarithmic scale screws with me too.

Here's their example picture:


Mind you this is much cleaner of a signal than I ever see in my own projects. But what is this telling us? How would you react if this were the analysis of one of your kick drum tracks? A hi-hat track? Bass guitar? Lead guitar? What does it all mean?!?

yeah that's my problem. I don't know what it means.
