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.

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.

Sometimes we need to include thirdparty libraries to add support to a new feature or simply to facilitate the development. With this tutorial we are going to explain some details to configure and be able to use a thirdparty library with a UE4 project. We also include an annex about how to deploy this libraries into an Android shipping.
