pulsemeeter VS AutoEq

There is also this for mixing in PulseAudio only github.com/theRealCarneiro/pulsemeeter I have tried similar methods to route audio streams in PulseAudio (using null-sinks and loopback-sinks) and never been happy with results, too much latency

I think most people use Voicemeeter Banana on Windows. This is similar but for Pulseaudio. https://github.com/theRealCarneiro/pulsemeeter

If you mean on linux then Pulsemeeter is literally the linux version of voicemeeter that uses pulseaudio

Here is a project that is an alternative to VoiceMeeter https://github.com/theRealCarneiro/pulsemeeter

You can use helvum to route audio. Helvum with Easyeffects covers most of the usage of voicemeeter. If you want similar type of UI like voicemeeter then check Pulsemeeter.

Pulsemeeter alternative for voicemeter banana.

There is also pulsemeeter for mixing in PulseAudio that is intended to be similar to Voicemeeter, but i would not expect it to be a good low-latency solution

If this bother you, you can check Pulsemeeter. It looks kinda similar to voicemeter banana.

There is another tool in development called Pulsemeeter. The goal is have similar UI and workflow like voicemeter banana.

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)
