Fader

Fader is a free, open-source application designed for macOS that provides volume control and audio output management directly from the menu bar. It enables users to adjust the volume for individual applications, switch audio output devices with a single click, and play audio on two devices simultaneously. The tool is intended for users who want a convenient way to manage audio settings on Macs running macOS 15 or later with Apple silicon.

Among its features, Fader offers per-app volume sliders, allowing for granular control over the sound levels of separate applications such as music players or web browsers. The interface displays active and available audio output devices, including headphones, speakers, displays, AirPlay targets, and Bluetooth devices. Users can easily select their preferred output, with the active device clearly marked. The application also supports drag-and-drop prioritization of output devices, letting users set which device should be used by default. When audio is played on multiple outputs at once, per-app volume control is temporarily paused, as indicated in the interface.

Fader is delivered as a menu bar app for macOS and can be installed via direct download or through Homebrew using a specified command. It is compatible with macOS 15 and newer versions on Apple silicon hardware. The software is distributed as free and open source, with no telemetry collected from users.
