In this tutorial, you’ll learn how to create a powerful granular synthesiser and auxiliary send effects system using MetaSounds. You’ll also develop a parameter-automated data table system in Blueprint, enabling the player character to dynamically modify synthesis parameters over time through the use of float curves and configurable data table row combinations.
This tutorial is designed to guide you from the fundamental concepts of granular synthesis through to the implementation of a fully automated procedural audio system within a game environment.
