Three real-time procedural monster voice synthesisers. No samples. No loops. Every growl, roar and creature cry generated live in Unity's audio thread, every single time.The demo scene is built using URP but the core synthesis is render pipeline agnostic, it will work in all render pipelines.Your monsters deserve better than looping audio clips.Our Procedural Monster Synths gives you three purpose-built procedural voice engines; Beast, Creature, and Roar. Each one generating creature vocalisations entirely in real-time from pure synthesis. No sample libraries. No repeated loops. No two sounds exactly alike.Beast models a biological throat from glottis to lips, gritty, organic, and alive. Perfect for wildlife, predators, and anything with a wet, physical growl.Creature is an expressive character engine. A full vocal tract simulation with dual distortion, five-formant shaping, and modulation. Built for bosses, aliens, and creatures with personality.Roar is built for scale. Layered oscillators, pitch sag, audio-rate tremolo, and multiband compression combine to produce cinematic monster hits that fill a room.All three engines share a voice management framework with scheduled triggering, sustain management, and a clean ScriptableObject architecture that integrates naturally with your existing Unity project.Your creatures will never sound the same twice.Beast, Creature, Roar: three independent synthesisers sharing a common audio DSP frameworkScriptableObject-based audio engines with audio thread command queues, DSP-thread-safe parameter updates, and priority-based voice stealing.Voice Management: Configurable polyphony per engine, token-based NoteOn/NoteOff safety, scheduled DSP-time triggering, sustain start/release APIDSP Features (Beast): Glottal simulation, FM feedback, aspiration noise, waveguide throat model, chest cavity resonator, three morphing formant filters, nasal notch, pitch envelope, growl LFO, asymmetric saturation, Haas stereo, release tail.DSP Features (Creature): Low Frequency glottal model, sub-octave layer, five-formant tract filter, dual waveshaping stages, subglottal resonances, waveguide comb, tremolo, formant wobble LFO, spectral tilt, breathiness release tailDSP Features (Roar): Low Frequency glottal oscillators, noise blending, pitch sag, parallel formant bank, saturation, tremolo, compressor, feedbackThis asset uses "Press Start 2P Font" under SIL OPEN FONT LICENSE Version 1.1, "Roboto Font" under SIL OPEN FONT LICENSE Version 1.1 and "Material Design Icons" under Apache License, Version 2.0; see "Third-Party Notices.txt" file in package for details.It wrote some of the documentation
