AudioPro Change Log

GS_AudioPro version changelog.

Logs

First release of GS_AudioPro, the premium half of the audio system. It requires GS_Audio and extends it.

GS_ProAudioManagerComponent subclasses the base Audio Manager and declares itself incompatible with it, so a project runs one or the other.
Pro attaches through the base gem’s accessor surface — engine, node graph, endpoint, mixing buses, shared Steam Audio context and HRTF — rather than reaching into internals.
GS_ProAudioSettings adds the geometry configuration alongside the base project settings.
Separate buses: AudioGraphRequestBus, AudioGraphPlayerRequestBus, AudioScoreRequestBus and the Klatt voice buses.
ScriptCanvas nodes under the GS_Play/GS_AudioPro category.

The .audiograph visual editor, built on the gs_graphcanvas framework with a data-flow topology.
31 node types: 4 sources, 7 filters, Echo and Reverb, 7 character and modulation effects, 4 utility effects, Mix and Split, three phase gates and the Output terminal.
AudioGraphLibrary (.agl) — named access to graphs, with a source-file picker.
AudioGraphPlayerComponent — drop-on playback with auto-play, spatialization and looping, and no handles to manage.
Preserve-until-release instance lifecycle: an owned instance quiesces to idle on stop and keeps its variables and configuration until explicitly released.
Full transport, variable, spatialization and state surface on AudioGraphRequestBus.
Node registration pinned against unity-build symbol stripping, so the launcher deserializes graphs.

ScoreArrangementTrack — multi-layer scores with time signature, tempo and fade control.
AudioScoreRequestBus: play a score with a chosen layer set, and bring individual layers in and out at runtime.

Formant text-to-speech with 3D spatial audio, backed by SoLoud and relayed into the audio graph through a custom node.
Voice profiles and phoneme maps as assets, with per-word pronunciation overrides.
Inline KTT tags for changing pitch, speed and waveform partway through a line.
Per-entity voice components with a segment queue and completion notifications.

Steam Audio scene and simulator integration, off by default behind a master switch.
Occlusion in raycast and volumetric modes, the latter giving partial occlusion at edges.
Listener-centric reflections with configurable wet mix, order and smoothing between rooms.
Reverb as a distance-independent send, so a room sounds consistent across its volume while the dry signal falls off.
Acoustic geometry components for authored volumes and O3DE Shapes.
15 acoustic material presets plus a custom material, including soft barriers that transmit rather than block.
Parametric reverb on a worker thread with lock-free direct and occlusion values.
