Technical Audio Design

ADVANCED
AUDIO
SYSTEM

A custom Unreal Engine 5 plugin built from scratch for production-ready character foley — GameplayTag-driven routing, Physical Surface detection, and MetaSounds playback, with Audio Insights tooling and dedicated editor workflows. Architected in C++ with full Blueprint exposure, on a subsystem framework designed to expand across additional audio domains.

Runtime Plugin

Foley Audio Subsystem

A dedicated C++ manager initialized by a central AAS_AudioSubsystem, communicating through a shared interface and GameplayTag events — built as the first and deepest subsystem of the framework.

01 / SUBSYSTEM
Foley Audio System
Socket-based raycast surface detection at runtime. Physical Materials mapped to GameplayTags, routed through surface and footwear bank maps to drive MetaSounds procedurally.

FRAMEWORK / ROADMAP
Designed for Expansion
The subsystem framework and GameplayTag event routing are built to host additional audio domains as they come online — proven in practice by RedCell, where the same patterns now run weapons, adaptive music, and UI audio in Blueprint form.

Architecture

Foley Signal Flow

How the system resolves which sound plays when a character's foot hits the ground — from animation notify to MetaSounds playback in four routing stages.

// Each footwear type has its own surface bank map — Sneakers and Boots resolve to entirely different sound sets per surface, enabling realistic layered audio without hardcoded logic.

Editor Plugin

Editor Tooling

A companion editor plugin built alongside the runtime system — bringing audio implementation and validation workflows directly into the Unreal editor.

Foley Animation Editor Tool
Foley Animation Editor Tool
Animation · Detection · Batch

Animation foot-strike detection, preview and validation of foley events, and batch operations for processing animation assets. Now grown into a standalone plugin with preset configs, sync-marker conversion, and an execution log.
