I have a MacBook Pro mid-2014 - 15-inch model. The speaker is making weird noise instead of proper bass. Doing a few trials I found out a suitable custom equalizer setting in a media player. When I am using this player and toggle this setting, the sound quality is a little bit better.
I was wondering if there is a way in which I can use this setting to the entire OS! so every sound including notification rings, alarms etc will have this effect that minimizes the creepy sound for me? If yes, how?
