Unified Audio Control is a native Swift/SwiftUI menu bar utility for macOS that keeps audio devices, system volume, and external monitor controls in one popover. It blends an Aggregate-device aware volume controller inspired by MultiSoundChanger with the proven DDC/CI stack from MonitorControl, resulting in a single place to manage speakers, headsets, and displays.
- Switch between every CoreAudio output device without opening System Settings.
- Control master volume & mute, even for Aggregate Devices that macOS refuses to show a slider for.
- Rename or hide devices you do not care about, and let the app automatically follow hot‑plug events for Bluetooth/USB hardware.
- Adjust brightness for both Apple-built panels and external displays using MonitorControl’s Intel + Apple Silicon DDC implementations.
- When a display is also the active audio output, a dedicated slider lets you send DDC volume changes from the same UI.
- Collapse/expand the list of displays straight from the popover, keeping the menu bar experience minimal.
- HUD overlays mimic macOS’ native brightness/volume heads-up display whenever you adjust sliders.
- A global hotkey (configurable in Preferences) toggles the popover so you never have to click the status icon.
- Preferences include launch-at-login, visibility toggles, and per-device/per-display custom names to keep lists tidy.
- Tested on Apple Silicon and Intel Macs running macOS 13+.
- Audio device switching, brightness control, and HUDs are functional today.
- Per-app audio routing is intentionally deferred until there is a redistributable driver solution.
- Clone the repository:
git clone https://github.com/akeslo/Unified-Audio-Control.git cd Unified-Audio-Control - Build/launch the menu bar app:
swift run
- Grant the requested permissions (Accessibility for hotkeys, Screen Recording for display metadata) when macOS prompts.
No third-party audio drivers are required—everything relies on CoreAudio and the bundled DDC helper.
