REAL-TIME AUDIO PROGRAMMING 101: TIME WAITS FOR NOTHING

Summary from the TLDR Web Dev newsletter

Real-time audio programming requires avoiding any code that might cause delays or unpredictable behavior, as such glitches would disrupt the smooth flow of audio data and lead to undesirable sound artifacts. People working with real-time audio need to understand worst-case execution times and avoid common pitfalls like locking, memory allocation, and external events within the audio callback function. To achieve seamless audio processing, employ lock-free data structures and atomic operations for communication between real-time and non-real-time contexts.
