If this isn’t enough, experiment with the “3X” and “4X” overdrive. A good starting point is to select the “2X” button under “Overdrive” and move the volume slider up.
Follow the steps below just once, and you’ll be ready to crank your speakers up to 4x their normal maximum volume* each time you open the program. The sheer power and simplicity of the interface is impressive. This software lets both audio professionals and hobbyists perform all kinds of useful tricks, such as recording Skype calls for podcast interviews and capturing the audio from a webinar. Being a full-time Mac user, I first discovered how to amplify my speakers with a program called Audio Hijack, from Rogue Amoeba.
