Finally, there is an introductory book on the theory behind Ambisonics and its practical applications:
From the preface:
Despite the Ambisonic technology has been practiced in the academic world for quite some time, it is happening now that the recent ITU, MPEG-H, and ETSI standards firmly fix it into the production and media broadcasting world. What is more, Internet giants Google/YouTube recently recommended to use tools that have been well adopted from what the academic world is currently using. Last but most importantly, the boost given to the Ambisonic technology by recent advancements has been in usability [..] the usability increased by plugins integrating higher-order Ambisonic production in digital audio workstations or mixers. And this progress was a great motivation to write a book about the basics.
The book is dedicated to provide a deeper understanding of Ambisonic technologies, especially for but not limited to readers who are scientists, audio-system engineers, and audio recording engineers. As, from time to time, the underlying maths would get too long for practical readability, the book comes with a comprehensive appendix with the beautiful mathematical details.
This book closes a big gap – I am not aware of any existing comprehensive introductory literature on this topic. So finally, a book I can safely recommend to colleagues who want to learn more Ambisonics. Beside the hardcopy, Franz and Matthias also managed to make the ebook version available as open access!
A new spatial audio book is about to appear: The Technology of Binaural Listening, edited by Jens Blauert.
The book includes contributions from 15 research laboratories in Europe and in the US which are part of the research initiative “Aural Assessment by Means of Binaural Algorithm” (AABBA). The table of content looks really exciting and I hope to get a printed version as soon as possible.
Between The Ahnert and The Blauert, there is a new book in my library: The Ahrens:
From the description:
This book treats the topic of sound field synthesis with a focus on serving human listeners though the approach can be also exploited in other areas such as underwater acoustics or ultrasonics. The author derives a fundamental formulation based on standard integral equations and the single-layer potential approach is identified as a useful tool in order to derive a general solution. He also proposes extensions to the single-layer potential approach which allow for a derivation of solutions for non-enclosing distributions of secondary sources such as circular, planar, and linear ones. Based on above described formulation it is shown that the two established analytic approaches of Wave Field Synthesis and Near-field Compensated Higher Order Ambisonics constitute specific solutions to the general problem which are covered by the single-layer potential solution and its extensions. The consequences spatial discretization are analyzed in detail for all elementary geometries of secondary source distributions and applications such as the synthesis of the sound field of moving virtual sound sources, focused virtual sound sources, and virtual sound sources with complex radiation properties are discussed.
Another gem is the accompanied website, where Jens provides the Matlab source code for all Matlab figures used in this book – bravo Jens.
