Prime Audio System
Production-ready audio architecture for Unity. Pools, entity channels, music crossfade, surface footsteps, RTPC, and VO queues — one clean service interface.

Prime Audio System provides a complete audio service layer for any Unity game genre.
Instead of placing AudioSources manually on every object, the system manages
per-category pools of AudioSources with priority eviction. Every Play() call
returns an AudioHandle that lets you Stop, Pause, Resume, or change the volume
of any specific sound after firing it — without holding a reference to the
underlying AudioSource.
Entity audio is handled through AudioController — a base class that binds
sound channels to an entity's transform in 3D space and automatically cleans
up all channels when the entity is destroyed.
Music is managed through MusicService with A/B crossfade and a Push/Pop stack
for pause menus and cutscenes. AdaptiveMusicSystem synchronizes multiple stems
at DSP time and transitions between game states by fading stem volumes.
Surface audio automatically routes footstep, land, and impact sounds through
a PhysicsMaterial/Tag/TerrainLayer database — including support for Unity Terrain
texture layers. Adding a new surface material requires only Inspector changes.
RTPC bindings connect any AudioParameter ScriptableObject to clip properties
via an AnimationCurve — engine pitch from speed, heartbeat volume from health —
with a single line of code in Update().
All dependencies are optional. The system works out of the box with direct
AudioClip references and a built-in event bus. Addressables support, custom
event buses, and custom surface providers can be plugged in at bootstrap time.
Suitable for: action games, horror, RPG, simulation, mobile, VR.
Requires: Unity 2022.3 LTS or newer, DOTween (free version).
