Per-app routing

Drag a running app onto the output device that should play it, then keep that assignment across launches.

Independent levels

Set an app volume and a device master volume without changing the rest of macOS audio.

Device control

Rename outputs, hide devices you do not use, and keep new apps on the default route.

Local audio path

Audio stays on the Mac. Network calls are limited to licensing and optional product notices.


How it works

A virtual output device backed by a native menu-bar router.

Mac Mixer installs a CoreAudio HAL plug-in that appears as the system output device. The companion app reads its loopback buses and forwards each app stream to the physical output selected in the popover.

Virtual device

Mac Mixer becomes the default output so app audio can be captured and separated.

Eight output routes

The current driver exposes eight loopback buses for simultaneous physical output destinations.

YAML persistence

Routes, custom device names, enabled outputs, and volume settings are stored in Application Support.

Licensing ready

The direct alpha supports a Stripe license path and local trial state.

Alpha release status

The current build is focused on per-app output routing, volume control, device management, and the direct license flow. The alpha installer is signed, notarized, and ready for Stripe/direct-license testers.
