DSP Processing

Block-based flow organization to ensure precision/stability

In a graph-based architecture, the audio-processing flow can be organized into fixed-size blocks (render quantum) driven by an authoritative sampling clock provided by the audio context or device. Each block advances a discrete time base in sample units and enables deterministic scheduling supported by a stable topological order, ensuring predictable execution.

This cycle avoids read-after-write hazards and guarantees that, given identical inputs and the same internal state, the output result is bit-exactly reproducible.

The model must maintain two views of the graph: one active and immutable during rendering, and another mutable on the control thread. Mutations (connections, disconnections, substitutions) produce a new topologically ordered version, which is atomically swapped at the start of the next block, avoiding locks and preserving cache locality.

Processing relies on a deterministic and synchronized render loop.

This block-based architecture ensures that audio maintains temporal stability. The result is a predictable, window-bounded latency in which each operation has a well-defined interval, ensuring that the graph is frame-accurate and fully reproducible.
