# Using Airfoil Speakers

With Airfoil Speakers, a free accompaniment to Airfoil, you can use Airfoil to transmit audio to other devices on your local network - Macs, PCs and Linux machines are all supported, as well as iPhones and iPods Touch. Now you can send music around your house without even needing an AirPort Express!
To get started, just install Airfoil Speakers on any device to which you wish to send audio. Once Airfoil Speakers is running on another device on your local network, that device will appear in Airfoil as an output and you'll be able to send audio to it. Below, we'll cover Airfoil Speakers for Mac, but Airfoil Speakers for Windows, Airfoil Speakers for Linux, and Airfoil Speakers Touch are all virtually identical.
You can download complimentary copies of Airfoil Speakers for Mac OS X, Windows, and Linux right from the Airfoil site. There you'll also find a link to Airfoil Speakers Touch, for the iPhone and iPod Touch.

### Airfoil Speakers Main Window

Airfoil Speakers Main window
When launched, Airfoil Speakers will appear with the window seen above, and also show up in your menu bar. You'll see Airfoil Speakers as an output in any copy of Airfoil running on your local network.
Once Airfoil Speakers is running on your receiving machine, you can send audio to it from Airfoil. It will appear and function with Airfoil just like a standard AirPort Express. Simply click the Transmit button next to the AirPort Speakers item in Airfoil's list, and audio will be sent out. Just like a physical AirPort Express, audio output is delayed by approximately two seconds.
If you're running a firewall, you may need to adjust it for Airfoil Speakers to work. For more details, see this page.
