I'm looking for software equalizer to enhance sound I get from my Windows 7 laptop, sadly Conexant High Definition Audio Driver does not provide such functionality. There are few solutions out there but I don't want to try them all, so what good equalizer can you recommend me?
EDIT: Just to make it clear: first, I listen to music through external set of decent speakers, not build-in laptop ones. Two, I'm looking for sort of system-wide, driver like plug which would enhance sound globally from any source, not specific player plugins (like proposed by mepher), nor player with equalizer function, I'm heavy Spotify user. By the way I used to have equalizer provided by Nvidia chipset driver on my old desktop pc and this makes world of difference in sound quality, why the hell this is not provided by system?
