vkBasalt VS NoiseTorch

there is vkbasalt for image sharpening. i don't know if it'll provide the image you want, but you can configure it and see if it fits your needs.

There is a alternative for Linux called vkBasalt. I haven't used it myself, yet, so I don't know how well it works. Your distro may have a package for it.

In the meantime, you can Generate a LUT yourself and apply it to games using ReShade or vkBasalt, but it doesn't apply to the system as a whole, takes a bit of work to use with each game, and there are certain games that won't work with it at all (rendering OpenGL games through Zink might help, but there are still gaps in its coverage afaik). All that effort is not for the faint of heart, lol.

The solution: vkBasalt

In the ticket there is also someone suggesting vkBasalt as a replacement.

The easiest way to do this on linux is to use vkbasalt with goverlay.

Noisetorch. https://github.com/noisetorch/NoiseTorch

Interesting! How does it compare with NoiseTorch/RNNoise?

Interesting! I'm currently using NoiseTorch-ng. Although NoiseTorch works well, I don't like that you need to reload NoiseTorch every time you change a setting.

I till now haven't figured out how to setup noise reduction in PipeWire. In Pulse, it was very easy. At the present, I'm using https://github.com/noisetorch/NoiseTorch.

(I do like PipeWire)

You could always try NoiseTorch. https://github.com/noisetorch/NoiseTorch

Maybe it will be possible to integrate this or something like this to SteamOS, given it's using PipeWire: https://github.com/noisetorch/NoiseTorch

If Apex allows you to select a mic, you can make a virtual (filtered) one with noisetorch.

Don't know if you are looking for the same - NoiseTorch - Works like a charm.
