    Comments about oreilly Instant Audio Processing with Web Audio:

    As the book claims, prior knowledge of HTML5, JavaScript and jQuery is required to understand the code. It is a good book for people who have some hands-on experience with the WebAudio API to brush up their skills. For someone with no idea about what the WebAudio API is, this might be a little difficult to grasp. Hands-on fiddling with the code examples will definitely help; the code being of high quality, it should also be a lesson on object oriented javascript.

    While reading this book, a little side by side googling is required to understand all the bits and pieces and that is a good thing as the quality of code is really good and it will help you understand how to structure your applications as well. The things that are possible with the WebAudio API is endless but this book covers the basic things well and slowly builds up to the final application which is cool. Graphs and diagrams have been added to clarify some concepts which helps.

    So read up on WebAudio API, build some simple apps with it, play around with the api and then get your hands on this book to sharpen your skills and get an idea on how to build a complete application using the api or integrate this with any other api, as part of a game maybe.
