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.
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.
In this short tutorial we are going to add a volume dialog to set the volume of the music and the SFX effects independently
