Audiout vs Airfoil, SoundSource, FineTune, SoundShare and SoundFerry.
Other Mac apps play to more than one speaker too. This page says where each one wins, and where Audiout does. Audiout is for the speakers you already own: every one of them on one screen, without learning a tool. It is not for Intel Macs, and not for shaping the sound of each app.

Trust.
One point each: Apple checked it (notarized, or sold on the Mac App Store), the source code is public, it was updated in the last 90 days, and the developer has shipped Mac apps before.

The short version.
- Audiout
Everything your Mac plays, on your AirPlay, Bluetooth and Chromecast speakers, in time with each other. Nothing to pick first, a fader per speaker, scenes in one click, and Bluetooth delay measured instead of set by hand. Apple Silicon only. Buy Audiout · €24.99
- Runner-up: Airfoil
Rogue Amoeba’s Airfoil ($35) plays to the same three kinds of speaker, plus other computers and phones, and has a phone remote today. You pick a source first and set Bluetooth delay by hand.
Common questions.
Is Audiout a replacement for Airfoil?
For playing everything your Mac plays to the speakers in the house, yes. Airfoil sends one source at a time, which can be one app or the whole Mac. Audiout sends the whole Mac by default and can send single apps to other speakers at the same time. Airfoil plays to more kinds of device, has a phone remote today and has run on Intel Macs; Audiout is Apple Silicon only.
Is Audiout a replacement for SoundSource?
No. SoundSource shapes the sound of each app: a 10-band equalizer per app, Audio Unit effects and microphone controls. Audiout has an equalizer per speaker and no effects, and adds Chromecast and measured Bluetooth timing. If shaping the sound per app is the job, SoundSource is the right tool.
Why pay for Audiout when FineTune is free and open source?
FineTune gives each app its own volume, equalizer and output, and does not play to AirPlay speakers. Audiout is built around the house: AirPlay, Bluetooth and Chromecast on one mixer, in time with each other, with scenes. Audiout’s source is public too. What you pay for is the finished build: signed with Apple’s Developer ID, notarized, and maintained.
How does Audiout keep a Bluetooth speaker in time with AirPlay?
It measures how late the Bluetooth speaker plays, with the Mac’s microphone or by ear, then holds the AirPlay speakers and the Mac back to meet it. Over a long session it watches for the Bluetooth speaker drifting and lines it up again. There is no delay slider to set by hand.
What about SoundFerry?
SoundFerry ($19) plays to AirPlay and Chromecast speakers, not Bluetooth. Its developer says it runs several seconds behind, so it is not for calls or games, and its trial stops playing if it cannot reach the internet. It sends the whole Mac to one group, with no per-app routing and no equalizer per speaker. Audiout plays to all three kinds of speaker, measures Bluetooth delay, and keeps playing offline.
What about TuneBlade?
TuneBlade is a Windows app. It does not run on a Mac.
What does macOS do on its own?
Apple’s Music app can play to several AirPlay speakers at once. Control Center cannot send the rest of the Mac’s sound to more than one, as Apple’s own support page says. Audio MIDI Setup can build a multi-output device, but it asks you to choose a clock source and drift correction, and it has no delay setting per speaker.
Get Audiout if the house is the point.
Everything your Mac plays, on your AirPlay, Bluetooth and Chromecast speakers, in time with each other. A fader per speaker and scenes in one click. €24.99 once.
Requires a Mac with Apple Silicon running macOS 14.4 or later. See pricing for what the licence covers.
