AppAudioConfig allows you to view and control the sound volume for every separate app.

This function is accessible natively from Vista forward only when the app is active, but AppAudioConfig just makes it a little easier to perform and doesn't require the app to be active. It displays the current audio settings for every application on your system and provides a simple option to change the setting of multiple apps at a single pass. You can change the mute/unmute status, sound volume levels, as well as the right/left audio balance of any application.

AppAudioConfig also includes the ability to search for a specific app through its simple search function. It is, as are the majority of Nirsoft's apps portable so you can always have the ability to modify app volume, etc., at your fingertips whenever needed.
