Runtime Audio Importer Documentation

Runtime Audio Importer is a plugin for Unreal Engine designed for Importing audio data in various formats into the game at runtime. It supports the following formats: MP3, WAV, FLAC, OGG VORBIS, BINK, and RAW (PCM).

Additionally, this plugin includes features for Transcoding and Exporting audio data in the following formats: OGG VORBIS, WAV, BINK, and RAW (PCM).
