v1.1.16

Deep audio support: the audio category becomes a full-stack authoring surface. Every audio asset is now creatable and wireable to a working state through the bridge - no empty placeholders, no manual editor steps.

Server

  • One-shot graph authoring. audio(metasound_author) and audio(cue_author) stamp an entire MetaSound or SoundCue graph from a single declarative JSON spec (nodes, connections, graph inputs/outputs, per-node defaults), instead of dozens of node-by-node calls. Connection endpoints use a compact nodeId:vertex form plus the heads input:<name>, output:<name>, audioOut:<channel>. Each element reports its own ok/error so a partial spec surfaces exactly what failed.
  • MetaSound graph authoring via the MetaSound Builder subsystem: add nodes by registered class name, add graph inputs/outputs, connect vertices, set typed input defaults, and build to the asset (metasound_add_node, metasound_connect, metasound_connect_audio_out, metasound_set_default, metasound_build, and more).
  • SoundCue graph authoring: construct and wire wave player, mixer, random, modulator, attenuation, looping, concatenator, delay, and switch nodes into a cue tree.
  • Mixing and routing: create submixes with parent hierarchy and effect chains (reverb, EQ, dynamics, filter, delay presets), sound classes, sound mixes with class adjusters, and concurrency assets.
  • Spatialization and assignment: create attenuation assets, and assign base submix, submix sends, sound class, attenuation, and concurrency onto any sound. Plus a reflection-based set_property for any audio UPROPERTY.

Internals

  • New handler files AudioHandlers_MetaSound.cpp, AudioHandlers_SoundCue.cpp, and AudioHandlers_Mixing.cpp; the bridge gains MetasoundEngine/Frontend/GraphCore, AudioMixer, AudioExtensions, and Synthesis module dependencies.
  • Verified in-engine against UE 5.8: full plugin build plus a live smoke pass creating MetaSound graphs, submix hierarchies with effect chains, sound classes/mixes/concurrency/attenuation, and routing assignment.

Bug fixes

  • Fix SoundCue property-key handling for the UE 5.8 change to FJsonObject key storage.
