* I have EQ Pro on my Mac. How do I use to adjust system audio for better sounding experience?

To make EQ Pro a system wide audio equalizer & amplifier, please install the audio driver that we developed on your Mac (you can download it by clicking here). After installing the that audio component on your Mac, in the app you select the source to "System Audio", and then you can use it to equalize macOS audios system-wide just like how you do which web audios.
