I remember reading about an application that allowed you to control the volume levels of individual applications separately. The program ran in the menu bar, and you could make your adjustments from there. I hadn't thought I would want such an application at the time, but have since found plenty of instances in which I had it (such as wanting to turn the volume off for my internet browser, while still listening to music, etc.). I've spent the better part of last hour searching for it, though, and haven't been able to find it -- which seems weird, since I had seen it recommended on multiple sites, and it appeared to be well-known.
Does anyone know what this application is, and where one might find it? I think the application's icon incorporated a pair of headphones, if that helps at all.
Thanks, and take care,
