dsp VS wlroots

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 😅

>barrier has been unmaintained for a long time.

As if not having new features added for 2 years makes it stop working? barrier is perfectly fine on normal linux desktop installs. I actually use synergy 1.x personally which has been "unmaintained" for much, much longer. Except synergy 1.x will compile and run on anything from windows 98 to ubuntu 5 to debian 12. You can't get a waynergy or inputleap to compile on an OS more than 2 years old. And even then, as you say, it's crapshoot if the particular wayland will have libei; many like sway are actively hostile to it and never will: https://github.com/swaywm/wlroots/issues/2378

It looks like they actually patched it to filter those modes out, so presumably it worked out of the box and was considered undesirable: https://github.com/swaywm/wlroots/issues/3038

I haven't experienced any of those. The video game performance hit may be due to vsync, but I don't play games so I haven't noticed.

You can however use tinywl. It is an example Wayland compositor that can't do more than displaying one application.

Sway/wlroots has implemented this, but I can't find any discussion for KDE.

wlroots is archived on github. Is it abandoned? Just saying, that only means they moved git hosts :-D

A lot of compositors are based no the wlroots lirbary. So they are still sharing the development effort and have a common base, its just in the form of a library rather than a display server.

gamescope use wlroots
