The mixer for your house.
Everything your Mac plays — Spotify, the browser, a game — on every AirPlay speaker you own, in sync.
Not just Apple’s own apps.
Only Apple’s Music and TV apps can play to every room. Audiout does it for whatever you play.
One click from the menu bar.
Every room, the same beat, for any device.
Audiout keeps speakers locked together. Go anywhere in the house — the music follows you.
Spotify in the kitchen.
Zoom at your desk.
Route each app somewhere different. Music fills the house while your call stays private.
The whole house, or just downstairs.
Save a set of speakers as a group, name it, and switch to it from the menu bar in one click.
One fader over everything.
Main Out is a ceiling; EQ shapes the tone underneath it.
70% × 80% = 56%
Your phone is a remote.
The iPhone app mirrors the Mac, fader for fader. It's a free download on the App Store with a paid unlock inside it, separate from your Mac licence.
The gear you already own is a system.
AirPlay, Bluetooth, Chromecast — Audiout speaks them all and keeps every speaker on the same clock.
- AirPlay
Supports both AirPlay 1 and AirPlay 2 devices.
- Bluetooth
Connect to a Bluetooth speaker and adjust its delay to keep it on the same clock.
- Chromecast
Connect to a Chromecast-enabled device.
Audiout handles the awkward parts.
Speakers that drop off, sleep and wake, your volume keys, first-run permissions — the things a multi-room setup normally makes you deal with.
- Lossless on the wire
Audio travels to your AirPlay speakers as Apple Lossless — not re-compressed on the way.
- Tune away the echo
A guided align-by-ear tool with a metronome tick finds each speaker's delay for you.
- Speakers don't silently vanish
A room that drops off stays in the mixer, with the reason why. It rejoins by itself when it's back. If sound stops anyway, Audiout falls back to your Mac and tells you what happened.
- Survives sleep and wake
Close the lid; when the Mac wakes, your speakers reconnect on their own.
- Your volume keys keep working
The keyboard keys macOS would grey out still move the house — and the speaker's own knob moves the app's fader.
- No cloud in the audio path
Finding speakers, routing and playback all stay on your network; the music keeps playing with the internet down.
- Keep an app off the speakers
Excluded apps are never captured — not even measured.
- Never blasts a room
New speakers join at a safe volume, and zero means true silence on every speaker.
- No drivers, no kernel extensions
A normal app with the usual first-launch permission prompts — nothing installed into macOS.
- Setup that explains itself
Guided first-run walks each macOS permission with a rehearsal of the exact dialog you're about to see.
- Works with VoiceOver
Labelled for VoiceOver, Reduce Motion honored everywhere, and contrast that's measured, not eyeballed.
- Signed and notarized
Built with an Apple Developer ID and notarized by Apple, so macOS checks it before it runs.
