Automatic Volume Mixer is a tool that allows automatization of Windows Volume Mixer based on user rules. You can open the Volume Mixer by right-clicking on the speaker icon in the system tray and selecting Open Volume Mixer. This application is an automatic version of that applet.

Common usage examples:

• Pausing your audio player (e.g. foobar2000) whenever any other application makes a noise, and resuming playback once the noise is gone. This enables you to keep your audio player running in the background at all times.
• Briefly muting all applications while a notification is playing.
• Forcing application’s volume to a set level.
• Automatically lowering volume during night.
• Launching processes / popups when some application makes noise.

Features:

• Detect volume levels of applications and act on that information.
• Fully configurable rules for detection, filtering, and executing actions.
• Ability to automatically adjust audio levels of applications.
