dsp VS JDSP4Linux

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 using JamesDSP with Pipewire. EasyEffects is the successor of PulseEffects for Pipewire.

PulseAudio/pw-pulse does not have a DSP host, but there is easyeffects/pulseffects and jamesdsp that has some DSP plugins. Not all the DSP you want may be available for processing audio

There is also JamesDSP

OK - I've uninstalled EasyEffects and am trying out JamesDSP. So far so good! Fingers crossed. Will update again after a couple of days of playing with it.

Also https://github.com/Audio4Linux/JDSP4Linux

It is an EasyEffects thing. Alternatively you could try out JamesDSP which from my experience i have not encountered this kind of problem.
