But the Time Capsule doesn’t have AirPlay. On AirPort extremes and expresses, there is a headphone jack, and when connected, you can wirelessly stream your music to your speakers from your iDevice.
I’ve had an airport express for a long time, but I stopped using it when I got my time capsule. After hearing about the AirPlay improvements, I decided to break the thing out.
The AirPort Express creates its own WiFi network, and if I’m connected to that then I won’t be able to backup to my time capsule. Luckily, it is now possible to plug the AirPort Express directly into the Time Capsule, and have them both work as the same wireless network. This means that I can stream music AND backup at the same time!
With this all settled, you will now see the AirPlay icon appear on all of your devices. From this point on, it’s all extremely easy. Just tap the icon and up pops a menu of all AirPlay devices on the network. Tap the speaker system you wish to stream to Voila, we have wireless music!
If you’re on a computer, however, you can only stream your music from iTunes. That is, of course, unless you have an app called AirFoil.
This allows any application on your computer to output sound to your AirPlay speakers.
However, there’s a small issue.
There is a two second delay between when you cause the sound to happen and when it actually comes out of your speakers. On the iDevices, the movies are in sync because they are decoupled 2 seconds back. When you change the volume on your computer, you will see the small notification popup, yet you won’t hear anything for two seconds. Quite annoying.
For videos, AirFoil has included the “AirFoil Video Player.” I don’t know if it’s very good, as I can’t even get it to work without freezing and crashing.
In general, this system is simple and functional. But if you’re trying to stream content from your computer, you will notice an extremely distinct delay. It’s not like that audio quality isn’t good, so all audio (including pandora and other streaming services) work fine.
