The Future of Audio in Unreal Engine
summary
A rewritten, multiplatform Unreal audio engine lands in UE4.15 and ships in Robo Recall with real-time synthesis and a new parametric reverb that stays constant cost while allowing dynamic dry/wet sends; it exposes a simple DSP plugin API so external source/submix effects (phaser, ring mod, delay, EQ) load as plugins and are controllable from Blueprint. Live demos include a subtractive modular synth, a granular synth, MIDI-to-Blueprint input, Steam Audio spatial/baked reverb integration, hot‑reloadable C++ synth components, and painless content-compatible switching across platforms.
