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.
A short tutorial explaining how to extract the frequency spectrum of a sound for our rhythm/music games using UE4 and the library FMOD. In a previous tutorial we have seen how to configure UE4 for using FMOD library now we can make some experiments using this library. We are going to make a visualizer for the frequency spectrum and a beat detector too.
