Real-time Confessions in C++: The Most Common “Sins” in Real-Time Code - Fabian Renn-Giles - ADC 2023

This talk examines the most prevailing misconceptions and frequent errors encountered when audio developers handle real-time code in C++. With my background as a contractor in the audio industry, I’m often called in to help fix subtle bugs in, or review code with real-time constraints. Yet, I see (and have myself made) the same type of mistakes over and over again resulting from a few common misconceptions of real-time C++ code.This talk offers an in-depth analysis of each of these misconceptions, debunking them with compelling examples from the audio industry.

Ranging from the ignorance of C++'s data-safety rules altogether, to the overuse of std::atomic and misbeliefs about the forbidden usage of locks and exceptions in real-time code, this presentation navigates the landscape between the theoretical rules of the C++ standard and real-world practical realities. This talk is an essential guide for developers seeking to avoid common pitfalls and write more efficient, reliable real-time code.
