Airfoil allows you to send any audio to AirPort Express units, Apple TVs, and even other Macs and PCs, all in sync! It's your audio - everywhere.

With Airfoil you can take audio from any application and send to your AirPort Express units, as well as Apple TVs, and even other Macs and PCs running Airfoil Speakers! Transmit audio from RealPlayer, Windows Media Player, QuickTime Player, and other media players. Send audio from web-based applications like Pandora, Last.fm, and other to the AirPort Express. You can even stream audio from audio devices like RadioSHARK, XM and Sirius radios, around your house.

What's New:

Version 5.12.2

• Preliminary Support for MacOS 15 (Sequoia) Betas
  Airfoil will no longer warn every launch when run on MacOS 15 (Sequoia). There are no known issues on Sequoia at present, but do note that these betas remain in flux. To avoid problems, we always encourage users to stick with Apple’s official (non-beta) OS releases.
• Return of the “Text to Speech” Special Source
  The “Text to Speech” special source has returned, to capture speech audio from applications which do not directly play generated speech (typically triggered by the “Start Speaking” command in the “Speech” menu) via their own process.
• Improvements to Special Sources
  The “Siri” special source now correctly includes sound effects on MacOS 14 (Sonoma), and the “VoiceOver” special source has been optimized to capture only necessary processes.
• If you’re running the latest version of Airfoil when you check for an update, the resulting information screen now provides a helpful “View Release Notes” button.
• Capture of audio played to secondary devices by VoIP applications has been improved.
• When Airfoil Satellite for Mac is receiving audio sent from an iOS device via AirPlay, remote control actions like play/pause no longer trigger an exception.
• Improvements have been made to the error shown when Airfoil tries and fails to connect to an Airfoil Satellite instance which requires a password.
• A crash which could occur due to the former “System Audio” source being renamed “System-Wide Audio” has been fixed.
• Improvements have been made to Airfoil’s debug logging.
• Airfoil 5.12.2 Is for MacOS 14.4 and Higher
  This variant of Airfoil supports MacOS 14.4 and higher. On MacOS 11 through 14.3.1, a different variant is automatically used, with no action required on your part.
