Here’s something I’ve been working on for a while and finally finished!

What is this?
Well, it’s a tool for your mastering process.

For those who aren’t familiar, an EQ Matcher is a tool, typically in the form of a plugin for your DAW, which allows you to supply a reference track that you want your song to “sound like” (that is, have the EQ pattern of), and then it will either supply the guidance for you to make adjustments, or offer to automatically make the adjustments for you.

The downside is that EQ Matchers can be expensive.
Another downside is that you often don’t really know what they are doing. It’s a sort of “Magic Box” that does some stuff and you get an end result.

This is where Manual Matcher comes in.
Manual Matcher takes the EQ spectrum information from a reference track and compares that against the supplied EQ spectrum of your song and offers suggestions for adjustment.

Since the system uses a 31 Band Equalizer template to do the calculations, It also plots this all out on graphs so that you can see how close you get. That way if you find that you need to fine-tune the EQ of your song a bit more (which is typical), you have something to base your adjustments on.

The instructions are included in the calculator.
If you have any questions, by all means please ask away!

One of the advantages that this has even over most EQ Matching plug-ins is that you can build your “ideal” reference track (called a “Seed” in the calculator) from up to three different reference tracks.

That way if you find, like myself, that you like the low end from one track, but the middle from another, and the high end from yet another, you can freely mix them together.

This is also pretty useful if you want to make an album and make all of your tracks the same EQ style and balance across the album.
In this case, you might choose one of your album’s songs as the reference track (seed) for the rest of the songs.

NOTE: This tool relies on you using Audacity. Make sure your Audacity Spectrum Analysis is set to a size of 32768. A reminder is noted on the SEED BUILD tab of the calculator. The 31 Band Equalization suggestions that the calculator makes are based on the frequencies that Audacity has in the Equalizer effect. (You can use your own equalizer just as well, but unless it’s a 31 band with the same frequency adjusters, the results may differ).

Hope this helps some folks!
As mentioned, let me know if you need any help and I’ll do my best to lend a hand.

OH, also.

The file is large, coming in at 10.5 Mb, so it may take time to load, and switching to the DETAIL CHART or the SEED BUILD CHART may stall a bit sometimes.

ALSO ALSO

By default, the file is locked and allows you only to edit where you need to make adjustments and enter data. This is to protect so you don’t accidentally mess things up.
However, for those who want to play around, by all means, feel free. Just open up the protection section in excel and enter the password “admin” to unlock the full access (note: some tabs are hidden, so you’ll have to unhide those extra tabs if you want to poke around at the calculation engine).

Cheers,

Very cool stuff! The idea of combining multiple tracks as reference is interesting, too.
I uninstalled Audacity a while ago since I wasn’t using it much, but if I find some free time I will give this thing a spin. Mostly using frequency matching with a very low mix percentage, just for some subtle modification in sound, but even that can have a big effect.
Impressive work!

You can model this in MM by using the adjustments on the far left. You can alter the seed by percent by frequency band; giving you a result of the seed as an influence but not a direct goal.

Out fucking standing!
since im currently EQ’ing a new track i shall peruse this audio witchcraft,and decide if i should gather the hoard for a burning…mostly just try it out.
oh and thanks…maybe…

Hey everyone, I haven’t used this myself (I have the real deal laying around with Ozone) but I can say I’ve been giving Jayson feedback on some WIPS and the EQ in them is almost universally a strong point. And this is his process. So I can (and do) vouch for the results if you’re willing to put in the effort.

Thanks for the vouch @White_Noise!

I look forward to what you do @Rixtr. :slight_smile:

One thing worth mentioning that I didn’t add before.

Audacity has a +20 to -20 dB limit on the EQ.
So, what I usually do is export the track LOW and then drop the SEED overall boost by at least 10 in the left setting.
Basically, I drop the seed until a part of it touches my LOW version of the song that I’m using.

This way, I still have lots of room to play with and the chances of exceeding 20dB needs on EQ adjustment are lower.

Then once I’m done, I push the original (er, by this I mean, the now equalized version…should have said “corrected version in progress”) back up, compress, and limit as needed until I see a LUFS reading that I’m looking for.

And then I drop the seed back to 0 and pull in my corrected version I just made.
ALWAYS save before starting the EQ and finalizing so you can redo it easily if needed.

If you try to do this all starting at -3 or -6 peak starting, you could run into trouble.

Cheers,
Jayson
