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

  1. Lynda - 开发iOS音频应用 音频应用,如合成器、调音器和播放器,都是App Store中最流行的应用。但即使是最简单的app,也经常会有古怪的声音。John Nastos,Metronomics的开发者,在本教程中演示他是如何使用iOS系统中的声音和播放控件编辑iOS声音应用的。他会分四个框架讲解:System Sound Services, AVFoundation and AVAudioPlayer, Audio Queue Services和Core Audio,这些为开发者提供了开始用来开发声音转换或将他们已有的技巧转换到另一种语言或平台的可能。 主要内容:使用System Sound Services播放声音;建立音频片段;使用AVFoundation和AVAudioPlayer播放声音;使用音频输入队列录制音频;回放声音;改变输入和输出级别;相应事件;处理第三方框架。
