AutoEQ Magic?

[jaakkopasanen]

Thank you for the great tool and database, I am a fan of it, have a checkout on my machine, and use it quite a bit.

Does this bring any improvements in terms of EQ quality -- achieving same corrections with fewer filters applied, or better fitting being achieved? I know a db here or there is not going to bring much difference, merely curious if this is just a performance improvement, or a potential quality bump as well.

On average the results are slightly better but might not be very audible. The new version is more robust though so it doesn't make big mistakes which the old one could do in some cases.

@jaakkopasanen - I just found that you published an amazing AutoEq v2.0.0 update - https://pypi.org/project/autoeq/
I see that installation tutorials are not yet updated, but this is superb improvement - so convenient and compact to install!

Now AutoEq is even more of a universal equalization/timbre-matching tool for all sorts of sound adjustments like here:

Mesh2HRTF-tools / Wiki / Earful_tutorial

sourceforge.net

(just see how easy it is to install now!)

Considering that AutoEq was already used in audio research:

the new version that is just 65KB-download will be even more useful beyond just Headphone measurements. I already have one more application in mind, in addition to Earful calibration by @pkane .

I've been considering how to go about it with this PyPi package. I thought building the measurement database into it but I think it will be better to bundle the measurements in a different way as a separate download. The PyPi package tailored readme documentation is on my to do list.

So I just started using Equalizer APO and AutoEQ this weekend. Its awesome.

I have settings for all of my cans besides my Sennheiser HD590. I owned a pair of 590s and the broke but a few years ago I was able to track down a pair in the original box and got them shipped over from England. Got a new cable, headband, and those awesome teardrop earcups.

Anyway they measure very similar to the HD650 in the bass and mids but sound way different in the highs.

I found a website that measured the HD590s and I was planning on making my own EQ by basically leaving the lows/mids the same as the 650 and then trying my best to lower the highs.

Anyone have experience making their own AutoEQ and want to help me with this?
Here are the 590s measured:

Here is the 590 vs the 650 taken from that site:

Here is the AutoEQ for the 650 I was going to use as a base:

I've tried it and Oratory1990 ( https://www.reddit.com/r/oratory1990 ) and I prefer Oratory setting. AutoEq much bigger library and I'm using that on my phone with Wavelet app.

I use wavelett in combination with Jaako's AutoEQ setting for my JBL tune 510BT. What i like about wavelet is the linear alteration that can be made on the found correction which creates maximum transparency for your liking. This JBL headphone is for bass heads but corrected with the AutoEQ setting using Wavelet it really make this headphone usebley for any kind of music. It makes me wondering that for just 49,99 you have a sturdy wireless headphone with an Amp, DAC 5.0 Bluetooth connection, phone functionality an running for 40 hours amazing. Wondering what @amirm will measure an his conclusion.

So I spent the night in a crash course on how to make your own AutoEQ for any headphone using outdate example commands.............but I got it to work

The Sennheiser HD590 is measured here:

From that site I used this graph:

I used a site that automatically enters data points and ended up with these data points after some trial and error

That turned into these AutoEQ settings for Harman 2019v2, no bass boost and used a +6 db bass boost per the AutoEQ settings, I was using commands for the outdated 2019 version of AutoEQ and they wouldn't even work so I just read the updated instructions and this seemed to work ok

Any suggestions on how to extract a frequency response from SoundID and import into AutoEQ?

So I've got Redmi Airdots 3 Pro, and unfortunately I can't find a proper measurement of them anywhere. I'd like to use them with AutoEQ. I did find out that they are in SoundID's database (so their mobile EQ app has a profile for it).

I'm wondering if it's possible to reverse engineer the output it gives me and get a frequency response? (Or enough data to feed to autoEQ).

My thoughts are to connect my phone to my pc and measure a sweep after the eq is applied. Assuming SoundID's "flat" studio profile is actually flat, surely this should give me the eq curve they used to correct my earphones?

Here's where I'm stuck, I'm not sure what to do with this data. I'm not sure how to really use REW. Would it be possible to flip the graph to give me the rough frequency response? And then I can input that into autoEQ?

Or at the very least I could just use this measured correction data in my own eq app (Poweramp equaliser), which would make my earphones "flat"?

And then I could add another layer of eq to get my desired sound signature?

Anybody with experience in REW and autoEQ/eqAPO/Poweramp, please help me out.

My biggest issue so far is getting the correction curve that I measured out from rew into poweramp or eqAPO (the values are way too high or too low if flipped.

Thoughts?

Thanks

@Svperstar, thanks so much for doing this!

Do you have PEQ settings for this? My best friend has a pair of Senn HD-590s, and he'd be thrilled to have them EQ'd. Thanks!

I'm currently trying to use this app to eq my SteelSeries Arctis Nova Pro Wireless for Xbox and I'm getting some strange results while switching between eq and non eq on the website. When I turn on the eq the music all of a sudden sounds distant and flat compared to how it sound without the eq on. It sounds like there's more detail in the music, but that it's being played further away from me than before. Is this expected behavior or am I supposed to somehow use the advanced knobs to fix this? I'm pretty new to equalization in general so any advice or information would be greatly appreciated.

Likely the equalisation includes some large adjustments (peaks) that need an offsetting reduction in output level. If so, you'll need to increase the volume on whatever device is driving your headphones.

Or possibly the eq adjustments are not to your taste or just plain wrong. But if it overall seems quiter /flatter it's likely a volume reduction.

In that case should I decrease the max gain on the autoeq app? When I do so it sounds better but the curve in the 5k area changes quite a bit from the target and looks more like the measured values.

No, if you want the adjustments to target but more "life" in the sound you will need to turn the actual amplifier up.

Share the actual eq you're using pls

 

[Astray]

Sure, here's what I'm seeing on the website:

When I decrease the max gain the sound gets awfully close to the original raw curve except for the base equalization. Like the peak at 4.5k becomes practically identical but with lower peak at 10k.

I'll be honest, I've no clue how that software works, what it is or how those 3 dials impact the eq settings

You can actually go to the website and play around with it yourself pretty easily. The website is autoeq.app and once you're there you can type in the same headphones I'm trying to eq and mess around the dial to see how it effects the "Equalized" curve.

can I ask why free field targets are automatically descarted? I might be missing something?
ISO 11904-2 difuse field target was added recently, but not the free field one

Free field target isn't really useful for headphones. Diffuse field is, but with a downward tilt..

the man here that is writing this really likes to experience things on his own. Do you know where he can find this target as a .txt or .frd?
