Windows audio, explained
Volume Control for Windows
A standalone volume mixer for Windows with per-app sliders and live peak metering. This site explains what the built-in tools already do, where they stop, and what a third-party mixer adds on top.
Each row is one app. One slider, one meter, one output device.
Reference
Beyond the Default Mixer
Windows has shipped some form of per-app volume for years. These are the specific gaps a third-party mixer fills, and each one has a guide of its own below.
Per-App Volume on Windows
Every app that is making sound gets its own slider, in one list, without opening Settings.
Move Apps Between Devices
Send each app to a different speaker or headset and keep system sound where it is.
Configurable Audio Hotkeys
Bind keys to open the mixer or change levels without reaching for the mouse.
Multi-Channel Peak Meters
Live level indication next to each slider, aware of multi-channel output, so you can see which app is making the noise.
Dark Mode & Accent Colors
Follows the light or dark theme you already picked, along with your Windows accent colour.
Available in 20+ Languages
Community translations cover more than twenty languages, with new ones added through Crowdin.
