Chapter 2 Further Reading

Everything below is real and checkable. Where a web address is given, it's a stable domain worth typing; where it isn't, the title and author will find it. Start with the Beginner tier — the single video there is worth more than most paid courses on this topic.

Beginner

  • Monty Montgomery, "D/A and A/D | Digital Show & Tell" (Xiph.Org Foundation) — found at xiph.org/video. A working codec engineer demonstrates this chapter's threshold concept on real analog test equipment: sine waves go into converters, smooth stepless waves come out, on an oscilloscope, before your eyes. About 25 minutes, free, and the single best antidote to stairstep folklore ever produced. If you watch one thing from this entire reading list, watch this.

  • Monty Montgomery, "24/192 Music Downloads… and why they make no sense" (Xiph.Org) — the essay companion to the video, hosted at xiph.org. The clearest written case for why high-sample-rate delivery solves no audible problem (including the ultrasonic intermodulation argument from this chapter), while being scrupulously fair about where high rates and deep bit depths genuinely earn their keep in production.

  • The Physics of Music (the companion volume to this book), Chapter 32 on digital audio — covers the same ground from the science side rather than the engineering side: the sampling theorem with more mathematical scaffolding, quantization treated formally, and the perception research behind "enough." Ideal if this chapter's intuitive treatment left you wanting derivations. Its Chapter 5 (psychoacoustics) also deepens the loud-hides-quiet hearing quirk that lossy codecs exploit.

Intermediate

  • Bob Katz, Mastering Audio: The Art and the Science (Focal Press) — the standard mastering text, and the best practitioner-level treatment in print of dither (several full chapters' worth of what this chapter gave one honest paragraph), word lengths, headroom, and level practices. Katz writes like an engineer who has had every one of these arguments and kept receipts. Will pay off again when you reach this book's mastering chapters.

  • Mike Senior, Mixing Secrets for the Small Studio (Focal Press) — referenced throughout this book; its early chapters on monitoring and session setup reinforce this chapter's "the famous numbers matter less than your levels and your room" hierarchy with small-studio realism.

  • Ethan Winer, The Audio Expert: Everything You Need to Know About Audio (Focal Press) — a sprawling, cheerfully myth-hostile reference with strong chapters on digital audio, converter performance, and how to design honest listening tests. Winer's blind-test methodology pairs perfectly with this chapter's exercises B4 and C2.

  • Hydrogenaudio (hydrogenaud.io) — the long-running community where lossy-codec listening tests are conducted with actual statistical discipline (ABX methodology, controlled comparisons). Browse the listening-test archives to see how transparency claims get verified rather than asserted — and to borrow their free ABX tools for your own tests.

Advanced

  • John Watkinson, The Art of Digital Audio (Focal Press) — the heavyweight engineering reference. Sampling, quantization, dither theory, error correction, converter architectures, and the full PCM-adaptor/video-tape history behind Case Study 1, at textbook depth. Not bedtime reading; definitive shelf reading.

  • Ken C. Pohlmann, Principles of Digital Audio (McGraw-Hill) — the other standard text, regularly updated across editions; particularly strong on delta-sigma conversion, noise shaping, and storage formats. Either Watkinson or Pohlmann will carry you as far into converter internals as a producer can usefully go.

  • Claude Shannon, "Communication in the Presence of Noise" (Proceedings of the IRE, 1949) and Harry Nyquist, "Certain Topics in Telegraph Transmission Theory" (1928) — the source papers. Shannon's statement and proof of the sampling theorem is shockingly readable for a foundational mathematics paper, and there is something clarifying about seeing the whole "is digital lossy?" debate settled in print before tape recorders were common.

  • Julius O. Smith III, Mathematics of the Discrete Fourier Transform and Introduction to Digital Filters (free online at ccrma.stanford.edu/~jos/) — Stanford's open DSP texts. The bridge between this chapter's plain-words sinc/reconstruction story and the actual mathematics, with audio examples throughout.

  • IEC 60908 ("Red Book") and ITU-R BS.1770 — the standards themselves: the CD audio specification whose birth Case Study 1 told, and the loudness-measurement recommendation underlying the normalization systems previewed in Case Study 2 (and detailed in Chapter 33). Standards documents are dry, but knowing they exist — and that the numbers in your dropdown trace to citable documents, not vibes — is part of the literacy.

For Educators

  • Build the lab around the Xiph video plus exercises B4/C2/C6. A 90-minute session that works: screen the Digital Show & Tell video, then have students run the 44.1-vs-48 blind test (B4) and the export ladder (C2) on their own material, and finish with the aliasing safari (C6) on a projector with a spectrum analyzer. Students who fail to hear a difference in B4 after watching the video have learned the chapter's deepest lesson experientially — design the debrief to honor that result rather than treat it as failure.

  • Audacity (free, cross-platform) covers every exercise in this chapter for students without a DAW: project rate and bit-depth settings, deliberate clipping, MP3 export at chosen bitrates, normalization, and spectrum views. No purchase should gate this material.

  • Hydrogenaudio's ABX tools (above) give statistics-literate classes a chance to run real blind protocols and discuss p-values in a context students care about — codec transparency claims make an unusually engaging statistics lesson.

  • Case Study 1 doubles as a history-of-technology seminar text: standards formation, path dependency, and corporate negotiation, with the 44.1/48 split as a live fossil students can verify in any DAW within seconds.
