Cool MacOS app to connect sound to any OS device.
Have you ever wanted to play audio on your Mac to your iPhone? You can't simply connect the phone as a Bluetooth device.
You need AirFoil
Things I Have Learned Using AirFoil
AirFoil is not the best tool for video playback. The sound will always be out of sync to the video clip, even if you use the audio delays.
The iPhone and Mac have to be on the same wireless network. If you don't see your iPhone in the device window it's most likely because it's not on the same WiFi network.
In addition, your iPhone has to have the iOS Satelite app open in order to be discovered.
You can pick the sound source to be from a specific application to the System Audio. The application is neat because you can play music from iTunes to an external device while keeping the local system sounds to the computer.
AirFoil allows users to adjust the sound volume on the device on the computer, so you can play music on the Apple TV on the other side of the house and control the volume.
