Airfoil can stream audio from any app on your computer via AirPlay.
Once installed, the software is incredibly simple to use. Any AirPlay devices on your network
should be available to it automatically. Each AirPlay device has its own volume control setting, so you
can set the volume for each AirPlay device from your computer or by using the Reemote app (no, not
Apple's Remote app) on your iOS device, which I'll get to later.
There are four very important reasons for using Airfoil to stream to AirPlay devices over iTunes
or the audio out setting on a Mac:
1. You can stream to multiple speakers.
2. You can stream audio from apps other than iTunes but not have to send all your system au-
dio to the AirPlay speaker as well.
3. Airfoil is compatible with a wider range of devices than simply AirPlay ones, and it even of-
fers a method to stream audio to your iOS devices — in effect, using them as their AirPlay
speaker. This capability reduces the cost of buying more AirPlay equipment if you attach
your iOS device to a docking station or speaker system and stream audio to it with Airfoil.
4. You can stream audio from other sources, such as radios, that you connect to your com-
puter.
Using Airfoil is easy:
1. If your computer is connected to the correct network and your AirPlay devices are switched
on, they should all appear in a list in Airfoil.
2. Click the unnamed button at the top of the Airfoil window (it displays the name of an applic-
ation such as Safari) and choose the application you want to use to stream audio from the
menu that appears (see Figure 3-9). If the application you want isn't listed, choose Other
Application and browse for the app you want to use.
