Small Signal Audio Design

Small Signal Audio Design is a technical reference book focused on analog audio circuit design and engineering principles. The book covers the fundamentals through advanced concepts of designing high-performance audio equipment. The text examines core topics including operational amplifiers, noise reduction, distortion minimization, power supplies, and equalization circuits. Each chapter contains practical examples, measurements, and real-world applications that demonstrate key concepts. Topics are supported by extensive measurements, graphs, schematics and mathematical analysis that enable readers to understand the principles behind audio circuit behavior. The book maintains a focus on achievable, cost-effective designs that can be implemented in both commercial and DIY audio projects. This work serves as both an educational text and practical handbook for audio engineers, with an emphasis on empirical testing and proven design approaches rather than theoretical ideals. The material synthesizes decades of audio engineering experience into actionable design strategies.

Readers describe this as a detailed technical reference for audio circuit design, backed by extensive measurements and data. Many cite it as their go-to resource for practical amplifier and preamp design. Liked: - In-depth explanations of circuit topology choices - Real-world measurement results and performance data - Practical focus on implementable designs - Clear writing style that explains complex concepts - Useful as both textbook and reference manual Disliked: - Math-heavy content challenging for beginners - Some say certain sections are too theoretical - High price point ($75-90 typical) - Limited coverage of digital audio Ratings: Amazon: 4.7/5 (89 reviews) Goodreads: 4.5/5 (12 reviews) Notable review quote: "The level of detail and experimental validation sets this book apart. Self doesn't just explain how circuits work - he proves why certain approaches perform better through actual measurements." - Amazon reviewer
