Free macOS installer that creates up to 8 independent virtual stereo audio devices based on BlackHole. Built for MDE — Mix Desk EQ, but works with any audio application.
Each virtual device acts as a stereo audio cable: audio sent to the output appears at the input of the same device. This is what makes advanced audio routing possible — Mix Desk EQ (or any app) sends a submix to a virtual output, and your target app picks it up as a regular input.
| Device | Purpose |
|---|---|
| MixDeskEQ System | macOS system audio → MDE input |
| MixDeskEQ WebRTC | MDE mix → Browser / video conferencing |
| MixDeskEQ Mix 3–8 | Additional outputs for OBS, recording, DAWs, etc. |
The installer lets you choose which devices to install via checkboxes. 2 devices are sufficient for most setups.
- Download the latest
.pkgfrom Releases - Double-click, authenticate, done
- Click Customize to choose which devices to install
After installation, devices appear as regular audio inputs and outputs everywhere — System Settings, OBS, Zoom, DAWs, any CoreAudio app.
An uninstaller .pkg is included in the release. It removes all MixDeskEQ audio devices and cleans up.
Requirements: Xcode Command Line Tools, Git
chmod +x build_installer.sh
./build_installer.shThe script clones BlackHole, compiles 8 instances with custom names, and packages them as a standard macOS .pkg installer with a matching uninstaller.
Because each output bus in Mix Desk EQ can feed a different virtual device:
- Bus 1 → speakers (physical)
- Bus 2 → virtual device → OBS picks it up as mic input
- Bus 3 → another virtual device → Zoom
- Bus 4 → yet another → recording app
Each path is independent, each carries a different submix.
