Introduction

Architectural principles and the context as coordinator

In this section, we will explore in depth the principles that define the architecture, examining how the audio context acts as the system’s coordination point, establishing authoritative parameters such as system topology, sampleRate and the audio-graph renderQuantum.

We will also see how these nodes interconnect to form a graph, where signals flow through defined paths and each block is processed deterministically.

We will examine how the engine ensures synchronization between components, preventing race conditions, and how resources are distributed to maintain stable latency.

Finally, we will discuss the philosophy that guides I/O: a modular, predictable, and extensible architecture designed to deliver sample-accurate processing, stability, and a solid foundation upon which to build effects and 3D audio processing.

The I/O architecture separates the context, nodes, and processing graph. The context defines global parameters, the nodes execute specialized DSP tasks, and the graph coordinates their communication deterministically, ensuring stability and synchronization.
