Free Equaliser software for Windows

is there some free equaliser app/software that equalises the Windows audio output?

I don’t mean some full-blow studio software that does editing and other. Just something that runs in the backgrounds (perhaps access through the system system tray) and equalises the audio being played.

Thank you

Yes, there are several, but this is the “Audacity” help forum and we don’t allow advertising for other products because it leads to lots of spam posts.
Try doing a Google search for “windows 10 equalizer free”.
