Three texts on Ambisonics theory:

1. Ambisonics Einführung (in German only)

Ambisonics theory is complicated, difficult to teach and not completed yet. Moreover the symbols and the formats used are not standardized. The text "Ambisonics Einführung" is an attempt to present some aspects of Ambisonics in a comprehensible way with diagrams and animations. The most important nomenclature and concepts are mentioned and compared with one another and the mathematical formulas and functions are explained. The text is available as a Mathematica Player notebook (download part 1) (download part 2) and as a pdf file (download).

2. Decoding Second Order Ambisonics to 5.1 Surround Systems

In this text the problems are described which arise by decoding B-format files for the asymmetric setup of 5.1 systems and different solutions are proposed. The text is only available from the AES.   M. Neukom, Decoding Second Order Ambisonics to 5.1 Surround Systems, in AES 121st Convention, San Francisco, CA, USA, 2006 (link AES)

3. Ambisonics Equivalent Panning AEP

This text describes in detail the panning which results from ambisonic en- and decoding. The text (only in English) is available as a Mathematica notebook (download) and as a pdf file (download). The results were first published in: "Neukom Martin, Ambisonic Panning, 2007, In AES 123st Convention, New York, NY, USA, 2007" (link AES) and "Neukom Martin, Jan C. Schacher, Ambisonics Equivalent Panning AEP, 2008, ICMC, Belfast, 2008" (download). In the downloads section you can find the implemtation as MaxMSP-External called ambipanning~ by Jan Schacher.
