dsp VS AutoEq

Thanks for detailed comment really apprentice it I found this https://github.com/bmc0/dsp which uses LADSPA API

DSP effects can also be implemented in ALSA via CLI using dsp (this would be closest to a systemwide solution, but does not support Bluetooth)

I guess you can use alsa's ladspa plugin host plugin and your favorite convolution plugin, but there obviously will be no graphical way to adjust any settings.

This SEEMS to be one formula for it, but I cannot decypher the gobbledegook https://github.com/bmc0/dsp/wiki/System-Wide-DSP-Guide

An Oratory1990 preset could help a lot. The stock tuning isn't too good. If you're using Windows, EqualizerAPO and Peace are a good EQ. I think that eqMac 2 will do it for Mac. Linux is a bit more complex to use/research, but maybe EasyEffects, pulseaudio-equalizer-ladspa, dsp, or LSP Plugins.

It took me a week to dial in the software side of my setup. NAS shared FLAC's -> Raspberry Pi -> RompR UI -> MPD -> bmc0's dsp for equalizing -> Asgard 2 -> Dan Clark Aeon Open X... and, ok, wow! I now see the appeal in spending an awful lot of cash and the time to fine-tune everything to perfection. I think it hit me when I kept wanting to turn it up because it just sounded so clear, but kept bumping it back down because I was afraid I was hitting some potentially damaging levels. Any other setup I've used was self limiting because of misbalance, a piercing treble spike for example would keep my enthusiasm in check.

If the latter, dsp, if the former look at the lsp-plugins collection. The latter will need Jack/Pipewire as I don't think Pulseaudio supports LV2 (it does support LADSPA for dsp).

Not very likely, the platform is simply too small for audio and gaming to justify the effort and cross platform development is limited when it comes to driver and audio/system APIs. I wouldn't hope for it anytime soon ): I think people wrote about Peace EQ, not sure if it has a Linux version.. otherwise pulseaudio+alsa, jack and calf/lsp plugins, maybe https://github.com/bmc0/dsp ..it gets very frickly very fast with audio on Linux if feel 😅

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)
