Reply to comment by FastGecko5 in Tried Oratory EQ on multiple headphones and prefer the default sound. by wiggan1989
Try manual Oratory settings from PDF. It's different than AutoEQ presets (even his).

I'm not saying it isn't, but why would that be the case?

AutoEQ just takes the measurements from various sources (like Oratory) and the software automatically makes the EQ preset correction. It's not the actual people like Crinacle, Oratory etc making these presets, they just provide the raw measurement data.
The Oratory PDF presets on the other hand, as far as I know, are manually crafted by him for every individual headphone.

It's exactly this. I once asked him that.

It's that, plus Oratory EQs to Harman, which AutoEQ does not, the default AutoEQ target curve you'll find in Peace, Qudelix 5K, etc has substantially less bass than Harman. This is why it kills the bass on basically all IEMs.
>None of these targets have bass boost seen in Harman target responses and therefore a +4dB boost was applied for all over-ear headphones, +6dB for in-ear headphones and no boost for earbuds. Harman targets actually ask for about +6dB for over-ears and +9dB for in-ears but since some headphones cannot achieve this with positive gain limited to +6dB, a smaller boost was selected.

It's extremely misleading that these curves are labelled as Harman, everyone thinks they are Harman but they are only Harman for the upper mids.
AutoEQ has also historically EQed too high up, and too much high up. This has been addressed in a more recent revision and the precomputed presets now limit themselves to a high shelf above I think 10,000Hz which is a big improvement. Oratory has historically taken a lighter touch in the treble.
Oratory's EQs also tend to be smoother and less extreme, with broader peaks, you can see there is a broad theme but the Oratory curve is smoother.
It's great software and works very well if you use it yourself manually but the precomputed target curves are junk, especially for IEMs. Took me ages to figure out exactly what it was doing. They are getting better, the introduction of low and high shelves is great. But Oratory1990's EQs still better.

What do you mean manually? They are automatic presets.

AutoEq is both a tool to generate EQ parameters to go from a source frequency response to a target frequency response, and a collection of EQ parameters (presets) generated with this tool. The problem is that the target frequency response used to generate the presets is (according to most people) crap. So the presets don't sound good. But AutoEq (the tool) can still be used to generate EQ params for the target of your choice, and does it very well.

You mean the function inside Crinacle's graph tool?
smalg2 t1_j67876q wrote
To be honest I don't think these two are the same. AutoEq is written in Python, Crinacle's graph tool is written in JavaScript, and they don't seem to share much code, if at all, or even to be developed by the same people. But yes, Crinacle's graph tool should do the job just fine.

So how do I use the AutoEQ manually for my own targets?
smalg2 t1_j69zusa wrote
Crin's graph tool, squig.link and others support a few targets by default (right below the chart) like Harman targets, IEF Neutral, Diffuse Field, etc. Select your headphones, your target of choice, press the AutoEQ button, and the tool will generate EQ parameters. Afterwards you can even tweak the generated EQ params and see the resulting frequency response curve (typical use-case is if you want more bass for example). This works really well. But if you want to use your own custom target, it looks like you need to use the actual AutoEq tool written in Python... I've never done this though. Actually the graph tools have an "Upload Target" button in the "Equalizer" tab which looks like it can be used for custom targets.
Edit: apparently you can also select another headphones' frequency response as a target. Nice!

Did it change so they provide it directly? It used to be that an image reading program was used and that is why sometimes the filters are in the wrong place.

Not sure :) By provide I meant that it's their measurements. I don't know if they are somehow involved with AutoEQ or what's the process.

I second this. The AutoEQ presets have been garbage and very different from his PDF's.
