Core Audio is the low-level iOS API for processing audio in real-time, used in games, virtual instruments, web radio clients, music mixers, and more. It also has a well-earned reputation for being a challenging and unforgiving framework. In this advanced all-day tutorial, we'll shake off the scary and dig into Core Audio, playing with its powerful pieces and cutting through its thicket of jargon and secrets disclosed only in header files.

The all-day class will be broken into four hands-on sections:

1. Sounds and Samples, Properties and Callbacks: the concepts of digital audio, the conventions of Core Audio, and our first audio apps

2. Pretty Packets All in a Row: Recording and Playback with audio queues

3. Dreaming of Streaming: Building a web radio client with Core Audio

4. Go With the Flow: Audio Units and Audio Processing Graphs

This is an advanced tutorial, and it is assumed that attendees are intermediate to advanced iOS developers. At a minimum, you should know how to build and run apps, link and use iOS frameworks, and be fairly comfortable with C code (including pointers and malloc/free). Of course, you should have a MacBook with Xcode 4.3 or higher. Being able to deploy to a iOS device during the tutorial is optional, but may be helpful.
