I've used pink noise fed through a tilt EQ then into SPAN. I used the tilt EQ to "level" the pink noise even more.
Why would you want to do this? Well, I did it so I could "model" my Michelangelo EQ's bells and shelves in TDR nova:) I also "modeled" the MAAG air bands.
I love span.
Slightly off-topic, but on the live audio side ~ I also like the SMAART Tools plugin for Audio Tools on my iPad while mixing FOH. That, along w/the Umik mic is killer. LOVE the Spectragraph and RTA. That lets me see "post" (what the mic is seeing in the room/sound of PA) and "pre" (the RTA's on the console showing the EQ curves before being sent through the mains).

I'm guessing you're using pink because white is not an option? I just use my tonegenerator or white noise plugin (stock Reaper plugs), then output to the gear, then back into another Reaper channel and use the spectrum analyzer plugin (stock reaper plugs) with the FFT turned way up.

Still needed a tilt EQ lifting the bottom even more to get a "flat" visual in SPAN.

...just got off a shift. Mixed a couple cool bands tonight. Anyway, had time to come back with some screenshots for you to see. I understand what you mean about white noise. It's more accurate probably at pin-poniting frequencies, but I'd rather have the octaves balanced and the desired visual before I feed it into any outboard EQ's to see how that react when I twist-away. I put up 3 screenshots. If you look at the oscillator, you can see which is white or pink. Also, you'll see the Slick EQ gentlemans doing the tilting towards the bottom even further away from white. See the reults in span. That said, my way is kind of "ghetto" and you probably know more than me and have a better way (which you mentioned). I don't know Reaper. I wish I did! I've checked it out a little but over the years and always thought it was awesome.

I've checked it out a little but over the years and always thought it was awesome. FYI, there is a "slope" knob in Span that will let you set white noise (or pink) to display as flat. Set slope to 0 dB for white noise, and 3 dB for pink.

@ Acegunn...I'm using the free version of SPAN. Unless I am just being a goofball, I don't see a control for slope on this version.
Either way, I did not know that and appreciate the tip!!! That would be a better way to do it.

I have the free version of Span also. The slope control show up in the "edit" menu. Attachments:

So exactly why do you need the numbers? Do you hear with your eyes? If you're ever going to develop your crtitical listening you need to give up the visual crutch and learn to trust your ear. As far as the echo box goes, without knowing what it actually is, you need to understand that just knowing what the frequency curve is won't give you the whole story, as a good deal of the tone likely comes from the harmonic distortion it generates which probably has more to do with the actual tonality than the frequency curve. You also need to understand that you can't use EQ to add on what isn't there in the first place, which is often the case with tape echos that have not been maintained properly (which most have not, these days.) And if you try to mimic the response curve of the unit with EQ you're missing a good deal of what makes a tape echo sound like tape. And a good part of the tone of the tape echos I've used is the compression effect that happens when you hit the tape hard. If your tape echo is a quality unit and you find it imparting a "drastic EQ" it probably needs service.
And why would you want to take a lot of effort to get a piece of gear mimic another piece of gear when you have the original gear? Seems a waste of time and effort to me.
I get that...but not all of us are screaming at clouds lol. I think I want to know so I can make it repeatable without having to wonder what the hell I used. I get what you’re saying, but it’s a convenience thing...I mean who wants a price of gear with 10 unlabeled knobs. They label them for convenience. And confidence. You have a point. The only thing is that knowing what the analyzer says the frequencies are in the target you're working to reproduce doesn't really mean that it's what you're getting when you try to reproduce that curve unless you do a similar analysis on the signal to be affected or use only EQs with fixed frequencies - which, of course, is why the best mastering EQs used switched attenuators. Regular potentiometers are neither consistent from unit to unit, nor do they maintain consistent settings on the same unit from one use to another. Close, perhaps, depending on the quality of the pot, but never exact. And if you're not after "exact", then it seems like a lot of needless work when you can get a ballpark setting by usual methods. As to wondering what the hell you used, well, you can take notes or even easily snap photos with one of them newfangled digital cameras.....
(yeah, I know - I don't document stuff like I should either a lot of the time....)
