Sound Control lets users use a software volume mixer. Control the volume of your apps independently. Opt-in apps to the system wide EQ with built-in and custom presets. Silence specific apps so you can focus. Set up hotkeys to control volume, mute and EQ for the foreground app. There is even a hotkey to mute all background apps. Add volume control to TVs and receivers connected to your Mac’s HDMI. All features are fully supported on El Capitan (10.11), Yosemite, (10.10) and even Mavericks (10.9).
