Airfoil enables you to send audio from your Mac to remote speakers all around your house. Stream to thousands of different outputs, including hardware like the Apple TV, Google Chromecast, and Bluetooth devices, as well as iOS devices, Macs, and PCs with the free companion Airfoil Satellite apps.

Airfoil can send audio from individual sources, rather than being forced to transmit all of your Mac's audio. Stream music from apps like Spotify, as well websites like Pandora. You can even stream from hardware audio devices like USB radios or microphones. It's your audio, everywhere.

Getting Started

This manual provides you with a useful overview of the application, including an outline of the interface, as well as details on using the application. We recommend a quick read-through, but you can also just dive in if you like. Refer back here for assistance at any time, right from Airfoil's Help menu.

Additional Assistance

The following resources will supplement a read-through of the manual and help you get the answers you need.

Information for Users of Previous Versions

If you've used any previous version of Airfoil, the additional information below may be helpful.

Using Airfoil

Getting started with Airfoil is easy. Read on for information on the main controls in Airfoil.

Airfoil's Main Window

Airfoil's Main Window

Airfoil's main window contains all of the essential controls to make transmitting audio with Airfoil a snap. Airfoil continuously scans your network to find and show any available output devices to which it can send audio. You just need to select an input source from the Source popup at the top of the window, then click the Transmit button next to each output you'd like to hear audio through.

From the main window, you can also adjust the volume at which audio is sent to each output, access the Effects window (see below) and view audio activity for Airfoil's currently-selected source with the level meters.

Output Sections

Airfoil's Output Sections

All available outputs appear in Airfoil's main window by default. At the top, you'll always see the Computer output, which enables you to play audio locally in sync with remote speakers. Below that will be Groups, if you've configured any (see below). The last section contains individual remote outputs - all the supported devices that are visible on your local network.

Speaker Groups

A Speaker Group in Airfoil

A speaker group makes it possible to send to multiple outputs at once, with a single click. For instance, you might make one group for all the speakers on the first floor of your home, and another group for all the speakers on the second floor. When you click the Transmit button for a group, all the speakers in that group will be activated. Click it again, and they'll all be turned back off.

Note that you can still adjust individual speakers within a group, toggling them off or on individually, and adjusting their volumes. Making a group simply provides a fast way to turn multiple speakers on or off.

To create a group, open Airfoil's Preferences and click the Groups tab. On the left side, you can click the + button to make a new group and give it a custom name. When you highlight a group in the list, the available outputs will show in the Speakers table on the right. Click the checkbox next to the speakers you wish to include in the group. You can edit or remove a group at any time using the Preferences window.

Effects Window

Airfoil's Effects Window

Airfoil's built-in Effects let you adjust audio as it's transmitted. Click the Effects button on Airfoil's main window to adjust the 10 band Lagutin equalizer, tweak the balance and adjust the global transmission volume for all outputs.

It's also possible to save custom equalizer settings. Simply adjust the equalizer to your liking, then select Save Preset As… from the Preset menu. Once you've saved a preset, you'll find it in the Custom Presets section of that menu. You can also remove custom presets by selecting Delete Custom Preset from the Preset menu.

Airfoil's Supported Outputs

Airfoil can send audio to literally thousands of different devices around your home. These remote outputs fall into several categories.

AirPlay

Airfoil began life in 2005 as a tool to send audio to the AirPort Express, the very first AirPlay device. Now, Airfoil can send to any valid AirPlay output, including the Apple TV, HomePod, and AirPort Express, as well as third-party devices from manufacturers like Bose, Sony, and many more. Configure your AirPlay device so that iTunes on your computer can see it, and Airfoil will as well.

Google Cast

With version 5.5, we’ve added support for sending audio to devices that support Google Cast. That includes all Google Chromecast and Google Home hardware, as well as many third-party televisions and steros. Just fire up Airfoil, and it will show all available Cast devices found on your network.

Sonos Hardware

Airfoil 5.8 added support for streaming to the newest Sonos hardware. If your Sonos device features AirPlay compatibility, it will automatically appear in Airfoil as an available output.

If you have older Sonos hardware, you'll be pleased to learn that adding a single AirPlay-compatible Sonos device is enough to enjoy audio on an entire system. Just group older speakers in with an AirPlay-compatible Sonos device like the Sonos One and they'll all receive audio sent from Airfoil.

Bluetooth

New in version 5, Airfoil can send audio to Bluetooth audio devices, like speakers, headphones, and headsets. Pair the device with your Mac via the Bluetooth System Preference, then make sure it appears as an audio output device in the Sound System Preference. Once it does, Airfoil will see it as well, and offer it as an output.

Software Outputs

To enable you to hear audio on other computers, we provide Airfoil Satellite, a free companion for Airfoil. You can run Airfoil Satellite on other computers, as well as iOS and Android devices. You can get more information and download free copies of Airfoil Satellite right from our site.

To get started, just run Airfoil Satellite on any device where you want to hear audio. Once it's running on another machine on your local network, that device will appear in Airfoil as an available output and you'll be able to send audio to it.

Airfoil Satellite for Mac is included as part of the Airfoil download. You can also download it separately from our site. Install it on any Macs on which you wish to receive audio.

Multiple Outputs Simultaneously

Airfoil isn't limited to sending to just one device at a time. In fact, it can stream audio to multiple output devices at once, all in sync. This works with any combination of devices, regardless of what type they are. Try it and hear for yourself!

Advanced Airfoil Features

The basic functionality of Airfoil is fairly straightforward. However, some more advanced features exist, and they're detailed on this page.

Menu Bar Mode

Airfoil's Display Setting

If you like, Airfoil can run exclusively in your menu bar, with no icon in the Dock or application switcher. To adjust how Airfoil displays, open the Preferences. From there, you can opt to have Airfoil appear in the menu bar, in the Dock, or in both.

Airfoil's Global Menu

When you opt to show Airfoil in the menu bar, Airfoil's global menu will provide access to its settings from any application. By default, you'll see the icon for the global Airfoil menu in the upper right of your screen:

Airfoil's Global Menu Bar Icon

Clicking this icon gives you access to Airfoil's most important functions no matter what application you're currently using.

Airfoil's Global Menu in Action

As you can see, the menu also shows information on what's currently being transmitted by Airfoil. Use the global menu to adjust and control Airfoil from anywhere on your Mac.

Advanced Speaker Options

The Advanced Speaker Options window can be accessed from the Speakers menu.

Airfoil's “Advanced Speaker Options” Window

Most users will not need this window, and are advised to leave it in its default configuration. However, it will prove useful for some users with advanced needs.

Hiding Speakers

Using the Hide Speaker checkbox, you can prevent an output from appearing in Airfoil's main window. This is useful if you regularly connect to a shared network which contains device you don't control. Simply turn that checkbox on, and they will no longer clutter up the main output list.

Adjusting Sync

Airfoil automatically keeps all outputs completely in sync, delaying audio to match all devices to the highest latency device. However, there may be rare situations where you wish to adjust this. For example, if an output is connected to a receiver which adds its own latency, you may wish to reduce the latency Airfoil applies slightly. It must be stressed that most users will not need to adjust this. It is generally advised to leave the Sync sliders in the default positions.

Statistics

The Advanced Speaker Options window also displays statistics for the current audio transmission to each active output. These can be useful for debugging problems. If you see a high attempted recovery number, or a high percentage, Airfoil is having difficulty reaching that device. This occurs when there's an issue on the network itself, and you may need to move your wi-fi router, or add extenders.

Preferences

Airfoil's preferences can be accessed from the Airfoil menu. The available settings are divided into three tabs.

General Preferences

Show Airfoil

Show Airfoil: This toggle determines how Airfoil's interface appears. By default, Airfoil appears in both the Dock and in the menu bar in the upper right of your screen. For more details, see the page detailing Airfoil's menu bar mode.

Play Local Audio Through

Play Local Audio Through: This setting adjusts the audio device through which audio from Airfoil's Computer output plays.

Remote Access

Allow remote speakers to connect to Airfoil: With this setting on, Airfoil Satellite will be able to request that Airfoil send it audio. Activate audio from where you want to hear it, instead of from Airfoil itself.

Allow remote control of Airfoil and audio sources: When this is active, commands can be passed from remote speakers to and through Airfoil. This will enable Airfoil Satellite to control Airfoil, toggling outputs on and off, adjusting their volumes, and even switching the selected audio source. As well, supported sources will be controllable, enabling you to remotely pause audio, skip tracks, or go back.

Software Update

Automatically Check for Software Updates: With this option activated, Airfoil periodically compares itself to the most current version available from our server and alerts you when a new version is available. Leave this on and Airfoil will help you stay up-to-date. You can also click the Check for Update button to initiate a check manually.

Groups Preferences

Groups Table: This table contains a list of all the groups you've created. From here, you can add a new group, remove a group, or adjust the speakers a group contains. For more information on Groups, see the Using Airfoil page.

Automation Preferences

Automatically Transmit To

Automatically Transmit To: When launched, Airfoil will immediately begin transmitting audio from the last selected application to the selected speakers. To turn off automatic transmission of audio, just uncheck any and all boxes.

Silence Monitor

Automatically disconnect from all speakers after [X] minutes: Turn this control on to force Airfoil to disconnect from any outputs if it streams silence for the specified time. This can be useful in situations where multiple people send to an output. Ordinarily, if a user forgets to disconnect, other users will be prevented from sending audio to the output. This setting will automatically disconnect the user after the specified time, enabling others to connect.

Purchasing Airfoil

Why should I buy Airfoil?

Put simply, you should buy Airfoil because it isn't free. We provide a free trial, so you can test out the program and all its features before you buy it. It's like test driving a car, for as long as it takes you to decide.

In trial mode, all of Airfoil's features are available to try, but it won't work for full-time use. During the trial, audio quality is degraded after ten minutes of transmitting.
