I am trying to understand how AirTunes actually works. It somehow sends my songs to a wireless device via iTunes and only iTunes. Shouldn't this also be possible via a different program?

It can't be so complicated, but I am trying to understand why it is possible with iTunes.

This question came from our site for professional and enthusiast programmers.

Note that because there can be some buffering and latency, it's not appropriate for interactive audio like games, live two-way audio chat, and system UI sounds. That's why it's not provided as a generic system audio output devices. – Spiff Apr 3 '11 at 17:14

It works like this.

It's a streaming audio protocol that Apple has implemented for a variety of its hardware and software.

There's nothing "special" about iTunes except that that just happens to be where Apple has implemented it.

Rogue Amoeba has a piece of software called Airfoil that implements this functionality and expands upon it outside of iTunes.
