Play audio on several devices at once.
Your Mac normally plays through one output at a time. TuningMac lets you add more from the menu bar: two pairs of AirPods, a set of speakers, your TV and your MacBook, all playing together, each with its own volume, EQ and sync delay.
- One-time purchase

Each device keeps its own volume, EQ and sync delay.
Watch a movie with two pairs of AirPods
Share one screen without disturbing anyone: connect both pairs of AirPods (or any Bluetooth or wired headphones), make one the main output and tick Also play through on the other. Each person sets their own volume, and each pair keeps its own EQ.
Fill the room with several speakers
For a party or a bigger room, play the same music through your MacBook, a Bluetooth speaker and the soundbar at once. Turn each one up or down on its own, so the far corner isn't too loud or too quiet.
Line up devices that play at different speeds
Bluetooth speakers and TVs add their own delay, so the same song can arrive at slightly different times and sound like an echo. Every extra device has a Sync Delay slider from 0 to 1000 ms in 5 ms steps: delay whichever device plays first until everything lines up.
Want a head start? Auto Sync (an experimental beta you turn on in Settings) plays a short chirp through each speaker and times it with your Mac's built-in microphone, then fills in the delays for you. Headphones are skipped, and you can fine-tune by ear afterwards.
Easier than Audio MIDI Setup
macOS does have a built-in way to combine outputs: a Multi-Output Device created in Audio MIDI Setup. It works, but it takes several steps, it has no EQ, and the keyboard volume keys stop working while it's selected.
- With TuningMac, you add or remove devices with one click in the menu bar.
- Each device keeps its own volume and its own equalizer.
- Switching which device is the main one doesn't interrupt the audio.
- Devices you added join again automatically when they reconnect.

Questions
Can a Mac play audio through two devices at once?+
macOS can, but only through a Multi-Output Device you build in Audio MIDI Setup, which takes several steps, has no EQ, and stops the keyboard volume keys from working while it's selected. TuningMac does it from the menu bar: tick each extra device and it starts playing, with its own volume.
Can I connect two pairs of AirPods to one Mac?+
Yes. Connect both pairs to your Mac over Bluetooth, choose one as the main output in TuningMac and tick "Also play through" on the other. Both play the same sound, and each pair has its own volume and its own EQ.
How many devices can play at the same time?+
Your main output plus up to 16 more. In practice you're limited by how many devices your Mac can keep connected at once, especially over Bluetooth.
Why is one speaker behind the others, and how do I fix it?+
Bluetooth devices and TVs add their own delay, often a few hundred milliseconds. Every extra output in TuningMac has a Sync Delay slider from 0 to 1000 ms: delay the device that plays first until they line up. An experimental Auto Sync (beta) can also measure speakers with your Mac's microphone.
Does each device keep its own EQ?+
Yes. Every device plays with the equalizer saved for it, so your AirPods can have Bass Boost while the TV speakers stay Flat.
Do devices rejoin automatically?+
Yes. TuningMac remembers which devices you added, and they join again when they reconnect.
