Märksõnad:

Developing Virtual Synthesizers with VCV Rack takes the reader step by step through the process of developing synthesizer modules, beginning with the elementary and leading up to more engaging examples. Using the intuitive VCV Rack and its open-source C++ API, this book will guide even the most inexperienced reader to master efficient DSP coding to create oscillators, filters, and complex modules.

Examining practical topics related to releasing plugins and managing complex graphical user interaction, with an intuitive study of signal processing theory specifically tailored for sound synthesis and virtual analog, this book covers everything from theory to practice. With exercises and example patches in each chapter, the reader will build a library of synthesizer modules that they can modify and expand.

Supplemented by a companion website, this book is recommended reading for undergraduate and postgraduate students of audio engineering, music technology, computer science, electronics, and related courses; audio coding and do-it-yourself enthusiasts; and professionals looking for a quick guide to VCV Rack. VCV Rack is a free and open-source software available online.

Arvustused

"Developing Virtual Synthesizers with VCV Rack is a great read; an informative read; an inspiring read; an empowering read; an essential read! This fantastic textbook and comprehensive set of applied audio coding tutorials by Gabrielli will become the basis of many college courses and foundational courses of study for every electronic musician interested in knowing how things work under the hood. With that knowledge and understanding they can code their own software synthesizers and DSP modules in VCV Virtual Eurorack format." Dr. Richard Boulanger, Professor of Electronic Production and Design, Berklee College of Music

"If, like me, you enjoy creating your own music tools, this book will help you bring your ideas to life inside the wonderful world of VCV Rack. Whether you are a beginner or an expert in DSP, you will learn something interesting or new." Dr. Leonardo Laguna Ruiz, Vult DSP
