I don’t know if such a mighty tool exists for WIN.
For LINUX you should use that system wide audio tool.
There are many things one could play around with.
I haven’t checked out all adjustments.
I have to play around with all these much more.
First I would like to point out a 30 frequency Eq.
Thats really more a normal user would need.
Here is a snapshot from the basses.
You should take a look at PulseEffects
If there is anybody who knows more about this tool and has some experience how to use it,
let us know.
I was installing some time ago a simple system wide eq, but this didn’t work properly
and “damaged” some audio adjustings.
So I was always a little sceptic to use such programs.
Now I found that very professional one. Nice GUI so far.
(But I like command lines also)
Absolutely great.
