audio-nodes

To implement a new Web Audio API node in React Native, instantiate a new AudioNode subclass following the GainNode reference pattern. This structured blueprint covers the node hierarchy, processNode lifecycle, and cross-thread communication end-to-end.

Audio thread processing in React Native requires strict rules: no allocations, no locks, and no blocking I/O. The processNode() contract enforces these constraints to ensure real-time audio rendering performance and prevent thread-safety violations.

AudioParam a-rate and k-rate processing in React Native audio nodes handle parameter automation at different granularities. The blueprint guides AudioParam handling within the processNode() lifecycle to ensure correct audio graph traversal and rendering.

Audio rendering artifacts in React Native often stem from violating the audio thread contract. Debugging requires checking for allocations, locks, or blocking I/O within processNode(), and ensuring proper preallocation in the node's constructor.

Cross-thread communication for React Native audio events uses CrossThreadEventScheduler and IAudioEventHandlerRegistry. These patterns manage event firing to JavaScript, ensuring safe data transfer between the audio rendering thread and the main thread.

Yes, you must preallocate memory in the constructor when building React Native audio nodes. This preallocation is required because the processNode() audio thread contract strictly forbids dynamic allocations during real-time audio processing.
