Apple Airplay (circuit, IC, something?)

Hi, I am working on an audio project and I would really like my device to be able to receive audio via apple airplay.

I am having a hard time finding any info on how to implement apple airplay.
An IC with AirPlay wireless receiver technology would be ideal.

I know that Denon, Marantz, bang and olufsen and B&W all have devices that can receive audio via airplay, but I don't know if you would have to be approved by apple, in order to get access to the technology?

It is not that easy.. You won't find a single IC that enables you to implement apple airplay. You need a wireless communication device (bluetooth/WiFi).. and some software (in a microcontroller) to implement the AirPlay protocol.

Here is one project which has lots of info for you.. unfortunately they did not succeed making the Apple AirPlay work, but maybe you should drop them an email and ask for advice:

Thank you misterT.
I did not expect it to be easy, and maybe i will not suceed and end up outsourcing it to a company who has experience with apple airplay, but before doing that, I would like to know more about, what I am dealing with.
I am an electronics engineer specialized in acoustics and digital signal processing. I can build the speakers, and code the crossover filters, room correction and so on to a DSP, but my skills in electronics might not be sufficient to do the entire project.
I will read the stuff you have linked to, thanks alot .

I'm not able to help you further (I know someone else can in this forum), but you gave some very important information about yourself and your skills. Without your second post everybody would have assumed you are a beginner (in everything). I think you can divide the problem to three parts: You need a wireless communication, a microcontroller to implement the AirPlay protocol and DSP, DAC etc. to output the audio. I believe you can handle it.. hard part is the AirPlay communication protocol and choosing the right hardware. Solve it piece by piece.
