Build System — Full Pipeline Audio Generator

Orchestrate all three layers (MetaSounds + Blueprint + Wwise) to generate complete game audio systems from a single description.

Process

Parse — Identify audio behaviours needed
Decompose — Map to MetaSounds (DSP), Blueprint (triggers), Wwise (mixing)
Generate — Build each layer using templates + knowledge
Wire — Connect layers (AudioLink, RTPC, events)
Validate — Check types, connections, paths

Available Patterns (10)

| Pattern | MetaSounds | Blueprint | Wwise | |---------|-----------|-----------|-------| | gunshot | Random → WavePlayer → Filter → Envelope | Fire event → trigger | RandomSeqContainer + reverb bus | | footsteps | Surface → TriggerRoute → per-surface chains | Line trace → surface detect | SwitchContainer + attenuation | | ambient | Looped layers + random details + LFO drift | Zone overlap volumes | BlendContainer + RTPC volumes | | ui_sound | Sine + AD Envelope (procedural) | UI event router | UI bus (non-spatial) | | weather | State-driven layers + crossfade + dynamic filter | Weather state reader | StateGroup + SwitchContainer | | spatial | ITD Panner + processing chain | Position tracking | Distance attenuation + HRTF | | vehicle_engine | Trigger Sequence → layered Wave Players + Compressor | RPM/throttle params | Engine bus + RTPC | | sfx_generator | 7-stage synth (Gen→Spectral→Filter→Amp→FX) | Parameter inputs | FX bus chain | | preset_morph | Morph 0-1 → MapRange → filter params | Morph slider | Blend preset bus | | macro_sequence | Graph variables → InterpTo → filter chain | Step triggers | Sequence bus |

MCP Tools

Single System

build_audio_system(pattern="gunshot", name="PlayerRifle", params={...})

AAA Project (6 categories)

build_aaa_project(project_name="MyGame")

Generates: player_footsteps, player_weapons, npc_footsteps, ambient_wind, weather, ui — each with dedicated bus, work units, events.

3 Execution Modes

| Mode | Condition | What happens | |------|-----------|-------------| | Full | Wwise + UE5 connected | Creates everything live | | Wwise-only | Wwise connected, no UE5 | Creates Wwise hierarchy + offline MetaSounds spec | | Offline | Neither connected | Dry-run preview of all layers |

Auto-detected from connection state. No config needed.

Cross-Layer Wiring

| Connection | From | To | |-----------|------|-----| | wwise_event → metasound_asset | Wwise Event | MetaSounds Source | | rtpc → ms_input | Wwise GameParameter | MetaSounds graph input | | bp → wwise | Blueprint PostEvent | Wwise Event | | bp → ms_param | Blueprint SetFloatParameter | MetaSounds graph input | | audiolink | MetaSounds output | Wwise Audio Input |
