Sound Control by Static Z Software
Per-App Volume Controls
Control the volume of your apps independently.
Add keyboard volume controls, to DisplayPort monitors, HDMI TV & Receivers, and other devices missing them.
Use a system-wide EQ or set a different EQ on each app. Each EQ can be 10 or 31 bands.
Touch Bar Support
Use the Touch Bar on your MacBook Pro to control app volume.
Adjust left/right balance for each app independently. There is also the option to down mix to mono allowing you to move all audio into your left or right channel.
Full Hotkey Control
Set up hotkeys to control volume, mute and EQ for the foreground app. There is even a hotkey to mute all background apps.
Per-app Audio Routing
Reroute app audio to any audio output device.
Send iTunes to an external USB device while the rest of your apps use your MacBook’s internal speakers.
Supported on macOS 10.11 – 10.15.x, including macOS Catalina.
