+Lock-free queues are the unsung heroes of audio software systems, quietly enabling ultra-low latency and thread-safe communication across a dizzying variety of scenarios. But just like navigating a multiverse, the world of lock-free queues is filled with many different variants-each with their own quirks, trade-offs, and hardware demands.
+
+In this talk, we’ll embark on a journey through this multiverse, starting with the simplest dimension: the single-producer, single-consumer queue. We’ll uncover why lock-free designs often outshine traditional lock-based approaches in real-time audio environments, and explore various implementations along with their pros and cons.
+
+From there, we’ll warp into more complex realities featuring single-producer, multi-consumer and multi-producer, multi-consumer queues. Along the way, we’ll tackle mind-bending concepts like memory ordering, cache coherence, and platform-specific behaviour.
+
+By the end of this adventure, you’ll have the insight needed to confidently select and implement the perfect lock-free queue for your audio projects-no matter how mad the multiverse gets.

 Memory safety issues in C++ have been discussed in great length over the past few years but a big corner of safety and security, thread safety seems to get far less coverage. Even in the current WG21 ISO proposals, most of the focus is on bounds, initialisation and lifetime, with little being said about thread safety.
