Globvler 4+

I love the idea behind this app. I often desire to mute one app while still having volume in another. This app will do that for you if you're not constantly changing apps. As I sit here trying to write a paper I am changing back and forth between Google Chrome and Pages. Some websites have noises, and I don't want to hear them; I only want to hear my iTunes songs. Changing back and forth between applications, however, defeats the Globvler app and returns to volume balance to normal.

If this problem could be fixed I would easily rate Globvler 5 stars. But, since it eventually failes its intended purpose, it is quite useless.

What does this app really do? i mean really. I downloaded it and nothing happens…

Right, Globvler doesn't mix sound output from different apps. So you can't mute one app while listening others.
You still have one volume control. It changes while you're switching from app to app.
I.e, you can select maximum volume for Screensaver and Minimum for Pages...
App does only change global volume, nothing more.

You need another app for this task. And you're not alone who want this.
In such case, that app will require a kernel extension or Core Audio plugins and root permissions to be installed...
It isn't allowed by current MAS rules.
