Airfoil 4.0

The kindly unicellular folk at Rogue Amoeba have released Airfoil for Mac 4.0, a substantial update to the company’s software for wirelessly sending audio from your Mac to other devices (including other computers, iOS devices, and Apple TV). Beyond its revamped interface, the new version of Airfoil packs in a variety of new features. Airfoil Speakers can now initiate connections back to Airfoil, so that you can start receiving audio remotely. And, with Airfoil Video Player’s new Web mode, you can watch Internet video and play the audio remotely, in sync. ($25 new, $10 upgrade, 11.1 MB)
