Learning Core Audio: A Hands-On Guide to Audio Programming for Mac and iOS (Paperback)

Audio can affect the human brain in the most powerful and profound ways. Using Apple’s Core Audio, you can leverage all that power in your own Mac and iOS software, implementing features ranging from audio capture to real-time effects, MP3 playback to virtual instruments, web radio to VoIP support. The most sophisticated audio programming system ever created, Core Audio is not simple. In Learning Core Audio, top Mac programming author Chris Adamson and legendary Core Audio expert Kevin Avila fully explain this challenging framework, enabling experienced Mac or iOS programmers to make the most of it. In plain language, Adamson and Avila explain what Core Audio can do, how it works, and how it builds on the natural phenomena of sound and the human language of audio. Next, using crystal-clear code examples, they guide you through recording, playback, format conversion, Audio Units, 3D audio MIDI connectivity, and overcoming unique challenges of Core Audio programming for iOS. Coverage includes: mastering Core Audio’s surprising style and conventions; recording and playback with Audio Queue; synthesizing audio; perform effects on audio streams; capturing from the mic; mixing multiple streams; managing file streams; converting formats; creating 3D positional audio; using Core MIDI on the Mac; leveraging your Cocoa and Objective-C expertise in Core Audio’s C-based environment, and much more. When you’ve mastered the “black arts” of Core Audio, you can do some serious magic. This book will transform you from an acolyte into a true Core Audio wizard.

音頻可以以最強大和深遠的方式影響人類大腦。使用蘋果的核心音頻（Core Audio），您可以在自己的Mac和iOS軟件中利用所有這些功能，實現從音頻捕獲到實時效果、MP3播放到虛擬樂器、網絡廣播到VoIP支持等功能。作為有史以來最複雜的音頻編程系統，Core Audio並不簡單。在《學習核心音頻》一書中，頂尖的Mac編程作家Chris Adamson和傳奇的Core Audio專家Kevin Avila全面解釋了這個具有挑戰性的框架，使有經驗的Mac或iOS程序員能夠充分利用它。Adamson和Avila用通俗的語言解釋了Core Audio的功能、工作原理以及它如何建立在聲音的自然現象和音頻的人類語言之上。接下來，他們使用清晰的代碼示例，引導您進行錄音、播放、格式轉換、音頻單元、3D音頻MIDI連接以及克服iOS Core Audio編程的獨特挑戰。內容包括：掌握Core Audio令人驚訝的風格和慣例；使用音頻隊列進行錄音和播放；合成音頻；對音頻流執行效果；從麥克風捕獲音頻；混合多個音頻流；管理文件流；轉換格式；創建3D定位音頻；在Mac上使用Core MIDI；在Core Audio的基於C的環境中利用您的Cocoa和Objective-C專業知識，以及更多。當您掌握了Core Audio的"黑魔法"，您可以做出一些真正的魔術。這本書將把您從一個初學者變成一個真正的Core Audio巫師。
