Like Greenbaum's previous work in this series, this book is packed full of articles on all phases of audio processing and synthesis. It is to the audio processing world what the "Graphics Gems" series is/was to the graphics programming world. Continuing the tradition from the first volume, this volume presents additional processing techniques, explores new areas, and teaches some basic concepts.
The book begins with a section of tips on how to make good recordings in various environments. The next section goes into the technicalities of sound synthesis, more precisely oscillator control and subtractive synthesis. Section 3 is a continuation from Volume 1, in that it continues with a discussion of basic signal processing operators like filters and transforms. A particularly interesting paper in this section is the concluding chapter, on integer arithmetic-based fast Fourier transforms.Section 4 is about spatialization. It doesn't exactly reveal what happens inside your Sennheiser Toltec processor, but it covers the basic ideas. Low-level must-know techniques, such as circular FIFOs and framing, are covered in some detail in section 5. Section 6 presents some popular tools, such as the SoX library,which is the swiss army knife of sound processing programs, and the wonderful synthesis toolkit by Perry Cook which is featured in his own book, "Real Sound Synthesis for Interactive Applications". It was a surprise to see a page on the QED package. QEDesign is an easy-to-use, multi-platform advanced digital filter design package. It is completely menu-driven and user intuitive, affording almost a non-existent start-up and learning curve. it is neither unique nor the best, but it's just a page out of the entire book. Music theory is the topic of section 7. This may be a foreign language for many engineers, as well as a foreign approach. For example, the authors explain what consonance and dissonance are, and how they fit in the sound scale, but there is no discussion of what physically happens, or, to be more precise, what psycho-physically happens. Auditory displays and auditory feedback are central to section 8, on sound design. The final section, section 9, reads almost like a Scientific American article on sounds in nature. It is very instructive. A very useful glossary of audio terminology concludes the book.
I highly recommend this book as a supplemental reference to anyone involved in the fascinating world of audio processing. However,this is really not for recording engineers, as there is much mathematics, signal processing, programming, and even some music theory involved.
