Audio apps, such as synths, tuners, and podcast players, are some of the most popular in the App Store. But even the simplest apps are usually wired for sound. John Nastos, the developer of Metronomics, shows how he uses iOS system sounds and playback controls to program iOS apps with sound. He walks through the four main frameworks—System Sound Services, AVFoundation and AVAudioPlayer, Audio Queue Services, and Core Audio—providing developers with the information they need to start working with sound or transition their existing skills from a different language or platform.

Topics include:

* Playing sounds with System Sound Services

* Setting up audio sessions

* Playing sounds with AVFoundation and AVAudioPlayer/AVAudioRecorder

* Recording audio with an audio input queue

* Playing back audio with an audio output queue

* Setting up audio units

* Changing input and output levels

* Responding to events

* Working with third-party frameworks
