Adjust the audio level to your hearts content using the Volume module.

Click the button in the lower-left corner of the program to run your audio through Audio Hijack.

Set your output device to “Internal Speakers.”.

Click and drag the “Output” module into the main window.

Repeat step two with the “Volume” module (under “Built-in Effects”.) Your main window should now look like this:.

Select the Application you’d like to make louder from the drop-down menu.

Click and drag the Applications block into the main window.

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.
