Use a computer or mobile device as an AirPlay speaker
If you are limited by the number of AirPlay speakers in your home or you don't have any, there is
another way to get involved in the AirPlay party. The brilliant developers of Airfoil have created a free
little app called Airfoil Speakers (see Figure 3-10) that can turn a Mac , a Windows PC , a Linux PC , an
iOS device , or an Android device into an AirPlay speaker. You must be running Airfoil on your com-
puter for Airfoil Speakers to work. Figure 3-10 shows an iPad receiving audio from a Mac via Airfoil
Speakers.
