Survival Horror Audio Director Toolkit (for Unity)

SCG Audio - Survival Horror Audio Director Toolkit (for Unity) is a

production-ready adaptive audio framework plus a complete survival horror audio

library, delivered as one working whole: content, state machine, runtime,

demo scene, and documentation. Drop it into your project and hear a designed,

tension-driven soundscape the same day — not a folder of WAVs.

Built entirely on Unity's native audio (AudioMixer + AudioSource). No FMOD, no

Wwise, no external dependencies.

Adaptive Music System

- 7-state music state machine (SaveRoom / Safe / Unease / Threat / Chase /

NoMusic / Title) with smooth crossfades; NoMusic silences music while

ambience and SFX keep playing.

- Dynamic music layering: 1 always-on bed + up to 4 synced layers per track;

intensity fades layer audibility instead of restarting layers.

- StemMix runtime control: mute/solo layers by index or label name.

- Designer-authored state transition fade times via a single

StateTransitionSO asset.

Adaptive Mixing (Intensity + HP)

- `SetIntensity(0..1)` drives synced music layer audibility and optional

music attenuation (configurable 0 to -12 dB on top of your own base volume).

- HP/Heartbeat drives a music low-pass filter: idle above the configured HP

knee, sweeping toward 800 Hz near zero HP.

- ConditionalPlayback: parameter-driven sound (heartbeat rate by HP,

breathing by gender) with String / Float / Bool parameter types.

Ambience & Reverb

- AmbientZone system with reverb presets (Off / SmallRoom / LargeRoom /

Outdoor / Cathedral), zone priority, and smooth enter/exit fades.

- Per-layer looping or random-interval ambient playback.

- StopAll / ResumeAll with zone-aware ambience suspend and restore.

Stingers & SFX

- Adaptive stinger banks (Death, Discovery LV1-LV3, Resolve, Door Unlock,

Game Start) with per-asset intensity gating.

- General-purpose one-shot SFX banks (`SfxBankSO`): clip variations, pitch

randomization, and per-bank mixer bus targeting — for gunshots, UI,

footsteps, impacts, pickups, and any category you add.

Designer & Editor Tools

- 9 custom inspectors covering the SCG Audio asset types, with use-case

tooltips, validation warnings, and multi-select editing.

- Custom Track Importer (Tools > SCG Audio > Custom Track Importer): drag

your own WAV/AudioClip assets to auto-create a MusicTrackSO and bind it to

a state — swap in your own music without touching code.

- One-click reverb snapshot repair utility.

- Demo scene with key-driven testing of the core runtime features.

- Included AI Skills: five source-verified guidance files under `Assets/SCGAudio/AI/Skills/` cover setup, content authoring, runtime control, ambience and reverb, and troubleshooting. Built following Unity's Publisher AI Skills guidance. These are optional development-time guidance files and do not run in builds.

Included Audio Content (the complete Audio Content Pack)

The bundled audio is a complete, human-composed survival horror library inspired

by 1990s classic survival horror games — the same 62-file Audio Content Pack

sold separately, included here in full. Not placeholder sounds: designed,

tension-driven cues ready to drop into your game or to swap for your own.

- 62 WAV files, 24-bit / 48 kHz stereo source masters.

- Music: Full Mix cues plus beds, intros, and stem/layer components for every

state — Chase (with a seamless loop and a stereo intro), Threat, Unease, Safe,

SaveRoom (Default + two variations), and Title.

- Ambience: layered loops for corridors, sealed rooms, and outdoor ruins.

- SFX: UI, item, gunshot, heartbeat, breathing, and demo footstep sounds.

- Stingers: Death, Discovery, Resolve, Door Unlock, and Game Start cues.

- Every WAV is composed and sound-designed by hand — no AI-generated audio.
