🔊 Sonant

Native Contextual Audio Manager for Unreal Engine 5

Sonant replaces scattered audio logic with a unified, data-driven pipeline. From physically accurate footsteps to dynamic room estimation, Sonant handles the complexity so you can focus on the soundscape.

✨ Features

🎯 Contextual Surfaces

  • Automatic surface detection via material names, physical materials, or per-face collision

  • GameplayTag-driven events - Define any audio event (Walk, Run, Land, Impact)

  • Smart caching - O(1) material lookup after first hit

  • Sub-mesh support - Different sounds for different parts of complex meshes

💥 Physics Impact System

  • Automatic intensity detection based on impact force

  • Light/Medium/Heavy categorization with configurable thresholds

  • Pitch and volume scaling based on physics properties

  • Micro-collision filtering - Eliminates jitter noise

🌊 Auto Reverb Estimation

  • 6-direction raycasting (Up/Down/Left/Right/Forward/Back)

  • Room size calculation with configurable presets

  • Dynamic Control Bus Mix activation

  • 2Hz update rate for optimal performance

🏔️ Atmosphere Zones

  • Priority-based mixing - Higher priority zones override lower ones

  • Reference counting - Proper handling of nested zones

  • Smooth transitions via AudioModulation

  • Volume component for easy zone setup

✦ Disclaimer: this plugin assumes a working knowledge of UE5 workflows, editor tooling, asset setup and so on. Custom integration, extension or modification may also require comfort reading and writing C++. If you are new to UE5 or plugin-based development, expect a learning curve. Before purchasing the Fab version, it is recommended that you explore the open-source GitHub version and the online manual first to understand the architecture, setup requirements, and integration style. This will help you determine whether the plugin fits your project and experience level.
