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.
With this tutorial we are going to show you how to use the FMOD library to load and play a sound into a UE4 desktop/mobile project. In a previous tutorial we have explain how to set project paths to be able to use a thirdparty library, now we can start coding a class to use this library.
