Ditto VS AutoEq

The most famous is the clipboard one (https://ditto-cp.sourceforge.io/). I'd be surprised if they were referring to another "Ditto" software.

Ditto works well for me. If you have a cloud based file storage service like Google Drive or Dropbox, put the ditto database file in that folder and you'll also have an auto backup.

In case you are not aware: https://ditto-cp.sourceforge.io/

For example: the wonderful Ditto Clipboard Manager is both an old-style .msi installer here https://ditto-cp.sourceforge.io/, but it is also on Crapstore here: https://apps.microsoft.com/store/detail/ditto-clipboard/9NBLGGH3ZBJQ?hl=en-us&gl=us

I highly recommend you use a clipboard monitor. I use Ditto (download link, Windows store link). It can help diagnose problems like this by letting you see the contents of the clipboard (using <`> after copying something.

I’ll use the opportunity to recommend Ditto. A great clipboard manager that also allows for easy pasting as plain text, white space removed, linefeed cleanups and more.

Looks like some sort of clipboard manager? I use Ditto, it's free I think and you can customize it to do all sorts of things with text/images you copy to the clipboard. https://ditto-cp.sourceforge.io/

I'm trying to follow this general process of EQing laptop speakers, which cites the AutoEQ Github wiki for digitizing a frequency response graph and converting it to CSV. The OP references converting the graphical data from an A-weighted scale to the dB scale, as well as interpolating more data points on their 20-frequency graph. Even without worrying about interpolation, I tried to follow the Github guide and just got hopelessly lost.

I have a topping dx3 pro+ and use https://github.com/jaakkopasanen/AutoEq/tree/master to play around with EQ's

jamesdsp/ An audio effect processor for PipeWire clients. It also uses presets from AutoEq.

what u can do do is go here https://github.com/jaakkopasanen/AutoEq/tree/master/results, pick and download the file for ur headphone and add it in APO equalizer as a second "graphic equalizer with variable bands" that will correct the first EQ with a curve made for ur headphone

Parametric EQ apps for Android can be googled, I use PowerAmp. The Qudelix takes care of all of that with its app to the point where you can load from a giant list of EQ sets they made from community data - Not all of it is accurate, better to go to the source. You can find EQ presets on the oratory1990 subreddit, Amir’s reviews for that particular headphone on Audiosciencereview and crinacle’s as well as rtings here: https://github.com/jaakkopasanen/AutoEq/blob/master/results/INDEX.md

I always recommended hearing before buying, but I'm assuming you can't try many in person so use AutoEQ to get an idea what you like - https://github.com/jaakkopasanen/AutoEq

https://rogueamoeba.com/soundsource/ (this has parametric EQ but it's a bit buried IIRC. It also has built-in support for AutoEQ according to this page so you might have to do almost nothing if you like the Harman curve)
