Airfoil is a software application that can transmit audio stream to various devices, such as AirPort Express, Apple TV, PCs and Macs. For instance, you can use it to play music in all the rooms of your home.

The interface of the application is simple and intuitive. You can get started by selecting the source between Internet Explorer, Firefox, Windows Media Player, VLC Media Player, or other application. Alternatively, you can pick the primary sound capture driver or stereo mix.

Airfoil allows you to adjust the volume, gain and balance, as well as to configure an audio equalizer if you don't want to apply a preset (e.g. Acoustic, Piano, Spoken Word, Vocal Booster).

You can link the program volume with the system volume, minimize Airfoil to the system tray area and select the device through which the app plays audio. But you may also allow remote speakers to connect to Airfoil or its audio source, enable the tool to automatically transmit sound to the computer, as well as enable Instant On. The latter option permits Airfoil to grab audio from the selected applications without having to exit or restart them.

The straightforward program runs on a moderate quantity of CPU and system memory, has a good response time and includes user documentation. No error dialogs have been shown in our evaluation and Airfoil did not hang or crash. Thanks to its intuitive layout and overall simplicity, less experienced users can quickly get accustomed to Airfoil's features.
