Audio Selector is a menu bar-only app — it doesn't appear in the Dock. Look for its icon in the menu bar at the top-right of your screen and click it to open the device list.
Yes. Audio Selector works with any audio output device macOS recognizes — built-in speakers, Bluetooth headphones, USB DACs, and audio interfaces. You can switch devices and change the hardware format (bit depth / sample rate) without opening Audio MIDI Setup.
Yes. In Settings › Devices, set the device’s Volume to Software and Audio Selector lowers the audio itself before it reaches the device, so the volume slider and mute work. For devices that report a volume control that does nothing, the keyboard volume keys work too. The volume is adjusted digitally, so playback is no longer bit-perfect while Software is on, macOS shows its recording indicator in the menu bar, and the device returns to its full level when Audio Selector quits. Requires macOS 14.2 or later. The built-in speakers, Bluetooth and AirPlay outputs don’t need it — their own volume always works — so the menu doesn’t appear for them.
Yes. Turn on “Show a section for switching input devices” in Settings › Devices and an Input Devices section appears in the menu, listing the input devices macOS recognizes. It stays hidden until you enable it, and only shows up when an input device is available.
Audio Selector lists exactly the formats your device reports to macOS. If a rate isn't listed, the device (or its driver) doesn't expose it. Some devices also lock their format while another app holds them in exclusive mode.
Install Audio Selector Remote on your iPhone or iPad, then on your Mac open Settings › Remote and turn on the remote daemon. With both devices on the same Wi-Fi network, the iOS app finds your Mac automatically. For advanced setups you can also enter the Mac's IP address and port manually.
The connection stays entirely on your local network — no external servers are involved. You can additionally enable 'Require Pairing' on the Mac so only iOS devices you explicitly approve can connect. In Settings › Remote, clicking the paired device count opens the list of approved devices, where you can name each one, see which is connected right now, and remove them individually.
When enabled, Audio Selector detects the output devices on your Mac that Roon is exclusively playing to and keeps their volume in sync — adjust it from Roon, from Audio Selector, or from the iOS Remote app. Volume changes are routed through Roon itself, so they work even while Roon holds the device in exclusive mode. The speaker icon on that device's row toggles the Roon zone's own mute, from the Mac or from the iOS Remote app.
Turn on 'Roon Volume Integration' in Settings › Volume › Integrations, then approve Audio Selector as an extension in Roon (Roon Settings › Extensions). A Roon server must be running on your local network.
Roon’s Volume Control Mode for that device is set to Fixed Volume, so Roon has no volume for Audio Selector to adjust. In Roon › Settings › Audio, open the device’s settings and set Volume Control Mode to DSP Volume — or to Device Volume if the device’s own volume control works — then open the Audio Selector menu again.
No. The integration is optional and off by default — every other feature works without Roon.
Yes. Purchase Pro once on your Mac and the iOS Remote app detects it automatically over the connection, giving you an ad-free experience on iOS at no extra cost.
On interfaces with more than two output channels, Output Pair picks which channel pair carries the stereo left/right — so you can send audio to outputs 3/4 instead of 1/2, for example. It appears above the format list for devices that expose multiple pairs, and Audio Selector puts your choice back when the device reconnects.
A Pro menu bar icon type that shows your volume level as a bar. It can display just the active output, every device at once, or Roon-playing devices — each with its own custom color. Choose it in Settings › General › Icon Type.
No. The app doesn't collect, store, or transmit any personal data. Everything runs locally on your Mac. See the Privacy Policy for details.
Only when you turn on Software volume for a device. To lower that device’s volume, Audio Selector has to process the audio other apps send to it, and macOS asks for System Audio Recording permission for that — which is also why the recording indicator appears in the menu bar while Software volume is on. The audio is processed in real time on your Mac and is never recorded, stored, or sent anywhere. If you don’t allow it, the device simply keeps its own volume.
