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.

Adamson, Chris, 1967-Learning Core audio : a hands-on guide to audio programming for Mac and iOS, Chris Adamson, Kevin Avila. This book wouldn’t exist without Kevin Avila and Mike Lee, who found a publisher who not only wasn’t scared off by the thought of a difficult niche Mac and iOS title, but actually relished the challenge of bringing this beast to market. They knew there was a crowd out there that has been aching for years to get Core Audio presented. in a practi-cal form that lets normal programmers draw out its ferocious power. Behind the scenes, Chuck Toporek championed this book, pulled me in when it got stuck, and saw it through to the finish.

Learning Core Audio book.

Thanks Chris Adamson and Kevin Avila two authors they created the book, Learning Core Audio: A Hands-On Guide to Audio Programming for Mac and iOS. This book let me have a gentle guide to walk through the basic of audio programming. Practice is the best way to learn something you are not familiar with. Therefore, I decided to use Swift to do practices on the original sample codes which were written in C/Objective-C. I wish I could learn more about unsafe Swift and also audio programming at the same time in this practice

A weekend with this book was better than two weeks of evenings fighting with the "documentation" that exists elsewhere. After working through the examples in this, you'll be able to fight your way through the CA reference documents to do new things. I highly recommend it, with no reservations.

That said, I have two criticisms of the text: their presentation of code snippets and the shallowness of their applications. The code itself is solid, with good references and such, but it's split up into a couple dozen of snippets for each chapter, which is kind of difficult to work with. It may be that it's impossible to present things in a better way, though. As far as the shallowness goes: as you build off their basic apps, you'll notice that things get a lot more complicated, rather quickly. I'm definitely glad they didn't throw us into the deep end of this right off the bat, but, at the same time, it's nuanced to integrate CA code alongside UI code. A simple drum machine or synth keyboard app would be really helpful, after showing us the trivial CLI apps.

On the whole, this is a fantastic and indispensable book, with a couple of things to improve to make it perfect. If you're looking at working with Core Audio, glance at Apple's documentation, then buy a copy. It will save you a lot of time and frustration.

This is long overdue as i got this book at the end of 2012. I read and worked through each example codeset once with both fascination and struggle. The struggle was a mix of both, what the authors', Chris Adamson and Kevin Avila, pointed out early in the read, that being this stuff, Core Audio, is not easy, and with programming I'm self-taught which has both blessings and curses in learning behaviors.

The book is written with reality 'how-to' and art, and I would add a sense of humor which keeps it from being a dry interpretation of Apple engineering. Though the latter is brilliant Apple's documentation is dense and cumbersome which in 'Learning Core Audio...' authors' Adamson and Avila took that brilliance and laid it out in somewhat baby steps and breadcrumbs which make the subject accessible and practical.

As pointed out early on, 'Learning Core...' is not a beginning programming book but an advanced topic that assumes both exposure with the C language, Mac OS, Xcode and Objective C. This said it had been several years since I had thought in the C language or any language for that matter till I began the journey with Objective C about two years ago. What I found however was that as I worked through the example code which I would say don't just download it, physically type it in and absorb it. After you see what the codeset will do manipulate it and see what else it will do. This approach has pushed me and given renewed programming confidence and I personally thank this book for doing that.

I will add to that, in my case some of the chapters and projects took me multiple reads to 'get it' partly as it's how I learn. In fact I'm still revisiting a great deal of the book for clarity and referral as I work through my own ideas and projects.

The only criticism I would make on this excellent work and this was through my experience which may have been my setup and version of Xcode as initially i was using 4.2 on Snow Leopard. I found on a few projects to get them to work I had to include framworks not mentioned in the example code. This may have been my oversight or misinterpretation but there were a couple of projects which appeared to only need the AudioToolbox framework and I found through trial error that I had to add ApplicationServices a time or two. I will say prior to this book all of my work with Objective C and iOS had been coding for graphical apps. The majority of projects in this book make command line Terminal or Xcode Console executables and not iOS apps. This said, the plus in that is you will learn to code for the OS X operating system as well as being able to move the code with some modifications in to the iOS world.

Bottomline Chris and Kevin's 'Learning Core Core Audio...' is excellent, inspiring and confidence building for those interested in delving in to this 'black box' of chip and voodoo mystery.

I've gone through a LOT of core audio-related code, samples, articles, blog posts and documentation and found myself spinning my tires a lot. I'm definitely an advanced programmer who has a background in audio, which is why I've always been so frustrated at Apple's lack of good documentation or samples on this.

This book changes all of that.

Extremely well written, will go deep when needed but not needlessly so. It's not for every programmer--you have to really love what you do, and love audio too--but if you fall into that latter category... a person who doesn't mind getting dirt under their nails, then you can absolutely make CoreAudio sing here (and if you've got the algorithm, you can do so literally!)

All in all an excellent, well-written book that will not disappoint!

iOS and OS X audio are done differently and the bulk of the examples work on OS X only. HAL methods (the methods with "Hardware" in their names) have been deprecated. I learned a lot from this book. Note to Chris Adamson, time for a new updated edition - this could be the definitive text.
