WebPlotDigitizer VS AutoEq

Are you looking for a digitizer tool like https://automeris.io/WebPlotDigitizer/ ? With the new AI tools being developed, I could see a tool like this being more automated.

If you’re only doing the one graph it makes more sense to just use an existing graph-to-data tool like this one.

There are several, yes. Here is one, and here is anther, and here is a third. There is a detailed comparison here.

Theory of Wing Sections by Abbott and von Doenhoff. Use a plot digitizer to extract data from published graphs.

If you don’t require complete accuracy you can try this for an approximation. https://automeris.io/WebPlotDigitizer/

At least in the case of Linux Debian, the cross-link to the project's homepage appears no longer accessible. Is it because the developer reorganized his web site? An alternative to scan the phase diagram can be Ankit Rohatgi's webplotdigitizer (Windows/Linux/Mac, can be used from the web browser).

There may the occasion you actually need the data from a publication, and want to plot them altogether with data newly collected data in one diagram in common. An overlay, though possible, can become tricky (scaling, centering, alignment, etc.) and plotting all data in a diagram generated from scratch (gnuplot/octave, matplotlib, Origin, ...) exported as an illustration in the usual formats (.pdf/.png), or pstricks/tikz is easier/more consistent with the material already compiled in your document. Then you like to reach out for a program like WebPlotDigitizer* to extract .csv data.

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)
