Audio Analysis Tools is an open-source plugin for Unreal Engine. Provides a variety of functions for analyzing audio data. Works in conjunction with the Runtime Audio Importer plugin.

How to install

There are two ways to install the plugin:

1. Through the marketplace.
2. Manual installation. Select and download the release for the required engine version, extract the archive into your plugins project folder to get the following path: "[ProjectName] / Plugins / AudioAnalysisTools". Afterward, regenerate the project files and rebuild the project.

When using the GitHub version, you must first install the Runtime Audio Importer as the plugin depends on it.

Warning! You don't need to download the Runtime Audio Importer separately if you installed the Audio Analysis Tools via Marketplace (because it's already built in).

Basic internal description

The plugin analyzes all data at runtime by feeding an audio frame to the analyzer while the sound is playing. The analysis uses data calculated by Fast Fourier Transform.

Example of detecting a beat as a sound wave is played

Live example

There is an example of a simple Android game that demonstrates the plugin's ability.
