How to programmatically improve sound in Linux distributions?

Question

linux

I install Linux on my computer to listen to music and watch movies.
My Windows even with DFX Enhancer sounds worse than Linux without settings (fedora, kubuntu)
On Linux, apart from multimedia and listening to music, I do nothing, so I want to improve the sound for more profit.
Of the methods that work and I tried there is PulseEffects - and also on the github there are presets for it with which the sound becomes much better and cleaner.
Who was engaged in optimizing sound in Linux, please discard the methods that you use.

Answer 1

Use ALSA instead of Pulse Audio.
