# RuntimeAudioImporter
This plugin will be useful for those who want to be able to import audio files of MP3, WAV and FLAC formats into the game in runtime (for example, if the game involves importing audio files from the player's device memory). It's easy to use in both C++ and Blueprints.

## How to install
Just extract the "RuntimeAudioImporter" folder into your plugins project folder to get the following path: "[ProjectName]/Plugins/RuntimeAudioImporter".

## How to use
 There are two ways to use this plugin: using Blueprints and C++:
 1. Blueprints. Just reopen your Unreal project and find a node "GetSoundWaveFromAudioFile".
 2. C++. Open your "[ProjectName].Build.cs" and find a block of ` PublicDependencyModuleNames ` or ` PrivateDependencyModuleNames ` (it depends on your needs). Add `"RuntimeAudioImporter"` String inside this block. After just include "RuntimeAudioImporterBPLibrary.h" using ` #include "RuntimeAudioImporterBPLibrary.h" ` where needed.

## Additional information
The in-memory audio transcoding operation is based on [dr_libs](https://github.com/mackron/dr_libs).
