With this tutorial we are going to learn how to apply Post process Effects to the scene. We are going to adapt one of the materials used in a previous tutorial Transition effects using materials to be able to use it with a post process volume and view the effect in all the scene.
With this tutorial we are going to add a beat tracking widget to our previous spectrum visualizer. We are going to improve this visualizer adding the average bars too and a song selector.
With this tutorial we are going to conclude the series about audio analysis using FMOD library and Unreal Engine 4. This time we are going to explain how to make a simple beat tracker in real-time. This algorithm will not be an universal solution for all the songs but is an aceptable approximation taking into account the process time limitations.
This tutorial implements a UE4 widget to visualize the spectrum generated in the previous tutorial (Part 3: Frequency spectrum), valid for Win64 and Android platform.
