Hi again, guys. Just a quick question: I’ve started to use convolution filters on Roon but have not been able to find the ones for my Grado SR325x headphones yet. Any hints about where I could find them? The best I’ve been able to do so far is to download some filters for Grado SR325i. Thank you very much. ---

This link will give you the AutoEQ recommended set zipped up and ready to go for Roon: [https://phones.killdozer.uk/api/filters/innerfidelity/innerfidelity\_harman\_over-ear\_2018/Grado%20SR325i](https://phones.killdozer.uk/api/filters/innerfidelity/innerfidelity_harman_over-ear_2018/Grado%20SR325i) Or you can scan for other sets here [https://phones.killdozer.uk](https://phones.killdozer.uk) They’re just derived from the project @AMT linked to. ---

Now I look there are four sets available for that model, earpad dependent ![Screenshot_20230419-224043](https://roon-community-uploads.s3.amazonaws.com/original/3X/a/4/a4b6b737701ef26d391554021ff18c21800cbd87.png) **Edit** I now realise I’m an idiot and those are not the Grados you’re looking for. No joy on your model sorry @Andrea_Lutri ![Screenshot_20230419-224233](https://roon-community-uploads.s3.amazonaws.com/original/3X/a/9/a92aa2b482935577af34e4943fa77c6db67ec284.png) ---

Thanks a lot, guys… Yes, the problem is precisely what killdozer was speaking about: there are no filters for the SR325X, which is quite strange as it’s a very popular model. I will try the ones for the SR325i, which should be similar, I think… or am I wrong? ---

I even checked here for you (you can derive filters from the data here) but no sign of that model. TBF they’re IEM focussed: > **[Squiglink - IEM frequency response database by Super\* Review](https://squig.link/headphones/)** > > Compare hundreds of frequency response graphs between IEMs and earphones from manufacturers like Moondrop, Sony, 64 Audio, Fiio, and more. ---

İf you don’t mind coughing up around $300, you can get a Minidsp Ears headphone measurement microphone and create your own convolution filters with REW. ---

Any alternate from this? I can’t acces [phones.killdozer.uk](http://phones.killdozer.uk) ---

Look at [https://github.com/jaakkopasanen/AutoEq/tree/master](https://github.com/jaakkopasanen/AutoEq/tree/master) and check out the readme to get what you’re looking for. BTW, does Roon [OPRA](https://community.roonlabs.com/t/introducing-opra-a-powerful-new-headphone-toolkit-for-roon-and-arc/285309) not supply filters for your headphones? ---

Hi @Dooms_Zero. Sorry, I put this up as it was problematic for quite a few folks at the time. There’s now an official dedicated app page: [https://autoeq.app/](https://autoeq.app/) which does the job with a bit more polish. I took it down during an online spring clean, meaning to restore it somewhere, but time and attention went elsewhere. This can be my unofficial sunsetting announcement 🙂 ---

Although, in truth, it’s more of a “lights have been out for some time now” announcement.
