Appendix D: Annotated further reading

A short shelf, ordered by what to reach for next. Open-access items are marked ⊚.

The one book after this book

Zotter & Frank, Ambisonics: A Practical 3D Audio Theory for Recording, Studio Production, Sound Reinforcement, and Virtual Reality (Springer, 2019). ⊚ Open access, and the field's standard text. Everything this book handled with intuition and sidebars — spherical-harmonic derivations, max-rE optimality, ALLRAD (Zotter & Frank are its authors), decoder theory, the kr limit — is derived properly here. Chapters 1–4 are the natural continuation of our Part II; its treatment matches the conventions AmbiTap uses.

Foundations

Blauert, Spatial Hearing (MIT Press, rev. 1997). The encyclopedic psychoacoustics of Chapter 1 — ITD/ILD, pinna cues, the cone of confusion, precedence — with the experimental record behind every claim.

Rayleigh, "On our perception of sound direction" (Phil. Mag., 1907). The duplex theory, from the source; a genuinely readable Victorian paper.

Gerzon, "Periphony: With-Height Sound Reproduction" (JAES, 1973). Ambisonics' founding paper — B-format, the energy-vector thinking, decades early. Historical but bracing: most of the field is already here.

Pulkki, "Virtual Sound Source Positioning Using Vector Base Amplitude Panning" (JAES, 1997). VBAP — Chapter 2's object workhorse and ALLRAD's second stage.

The specifics this book leaned on

Nachbar, Zotter, Deleflie & Sontacchi, "AMBIX — A Suggested Ambisonics Format" (Ambisonics Symposium, 2011). ⊚ The AmbiX specification: ACN, SN3D, and the FuMa conversion tables format~ implements. Short; read it once and Chapter 8 becomes obvious.

Zotter & Frank, "All-Round Ambisonic Panning and Decoding" (JAES, 2012). ALLRAD — the construction behind Chapter 12's flattest curve.

Schörkhuber, Zaunschirm & Höldrich, "Binaural rendering of Ambisonic signals via magnitude least squares" (DAGA, 2018). ⊚ MagLS — why hrtf_dataset magls sounds the way Chapter 13's figure shows.

Allen & Berkley, "Image method for efficiently simulating small-room acoustics" (JASA, 1979). The image-source model behind room~'s early reflections and Chapter 11's reflectogram.

Gardner & Martin, "HRTF Measurements of a KEMAR Dummy-Head Microphone" (MIT Media Lab TR-280, 1994). ⊚ The measurements inside binaural~.

Majdak et al., "Spatially Oriented Format for Acoustics (SOFA)" (AES convention, 2013; standardized as AES69). The HRTF container of Chapter 13; sofaconventions.org hosts the public databases (HUTUBS, ARI, SADIE II) worth auditioning.

Tools and communities

The IEM Plug-in Suite documentation (plugins.iem.at) ⊚ — besides documenting Chapter 20's reference suite, the plugin manuals are a compact course in production ambisonics by the group that wrote the textbook above.

The SPARTA papers and site (leomccormack.github.io/sparta-site) ⊚ — Aalto's suite, with citations into the parametric-spatial-audio research frontier (COMPASS, HO-DirAC) when you want to see past linear ambisonics.

AmbiTap's own documentation ⊚ — this book deliberately didn't duplicate it: docs/CONCEPTS.md (the conventions and the real-time contract), docs/COMPARISON.md (the measured cross-library verification — how we know the numbers in this book's figures match independent implementations), and the executed notebooks in notebooks/ (every algorithm, visualized and asserted). The figures in this book regenerate via scripts/generate_book_figures.py.

Where the practitioners are (2026): the Sursound mailing list (venerable, active since the '90s), the IEM and McGill communities' public materials, and the game-audio side's GDC audio talks ⊚ for Chapter 21's world in practice.

If you read only three things

  1. Zotter & Frank (the book) — theory, properly.
  2. The AmbiX paper — ten minutes, permanent immunity to Chapter 8 problems.
  3. Blauert — because every renderer in this book is ultimately an argument with your auditory system, and Blauert is its biography.
