Module engine 

Audio engine — RCU-based real-time audio processor.

The engine owns the audio graph and processes it in the audio callback. Graph mutations happen via clone-modify-swap (Read-Copy-Update) using arc-swap. The audio thread never blocks, never allocates, never locks.

Structs

AudioEngine

The main audio engine. Owns the graph via ArcSwap for lock-free access.

EngineConfig

Configuration for the audio engine.

GraphBuilder

Builder for constructing audio graphs on the main thread.

GraphSnapshot

An immutable snapshot of the audio graph, shared between threads via Arc. The audio thread reads this; the main thread clones, modifies, and swaps.

Functions

swap_graph

Swap a new graph into the engine atomically. Call from main thread only.
