A More Intuitive Approach to Optimizing Audio DSP Code - Guiding the Compiler

Explore an intuitive approach to optimizing audio DSP code in this 45-minute conference talk from the Audio Developer Conference 2023. Learn how to guide the compiler to optimize code efficiently without sacrificing readability or maintainability. Discover techniques compilers use for optimization, useful patterns and anti-patterns, benchmarking methods, and how to identify different types of bottlenecks. Examine case studies comparing performance and generated assembly code before and after optimization. Gain insights into optimizing small, tight loops of audio DSP code running from cache, and compare the performance of C++ standard library functions to custom implementations. Access a companion GitHub repository to further explore the concepts presented in this talk aimed at audio developers seeking to improve their code optimization skills.
