Global Delight recently updated their Audio enhancing software to be compatible with Mountain Lion for Mac. If you haven’t checked out Boom yet, you should. It enhances the stock Macbook speakers along with any other speakers you may have connected to your Mac. Boom allows for multiple pre-sets or profiles to be saved for different listening conditions or speaker set ups or media apps. Check out the links above for the app and if you already have it but haven’t updated yet just run the app and Notification Center will advise you of the update.
