Crate forge_audio 

forge-audio

Zero-allocation, lock-free audio architecture for real-time DSP, game engines, and WebAssembly.

Architecture

• Lock-free mixer with crossbeam zero-contention design
• 120-frame rollback buffer with 18-byte packed diffs and Blake3 checksums
• Double-buffer VRAM staging for CPU→GPU audio visualization
• Integer-deterministic audio for networked game engines
• Phase-aligned beat sync for tempo-locked mixing
• ~269KB stack-allocated footprint — no GC, no heap on the hot path

License

This crate is dual-licensed:

• AGPLv3 for open-source and non-commercial use
• Commercial B2B License for proprietary/SaaS/cloud integration

Modules

diff_pool

WavDiff + DiffPool + RollbackBuffer — 18-byte diff protocol with pre-allocated ring buffers for deterministic rollback.

dsp

DSP primitives: load, effects, write.

engine

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

graph

Audio processing DAG — directed acyclic graph with topological sort.

limiter

Brickwall look-ahead limiter for speaker protection.

metering

Production-grade audio metering: true peak, RMS, phase correlation.

realtime

Real-time audio output via cpal. Lock-free SPSC ring buffer path only.

rt_safety

Real-time safety enforcement.

stubs

Stub types for modules not included in the public release.

viz_buffer

AudioVizBuffer — lock-free shared memory between audio and render threads.
