Runtime Audio Importer (MetaSound)

Advanced runtime audio processing plugin for Unreal Engine with MetaSound support.

ℹ️ Note: If you have the regular RuntimeAudioImporter plugin installed, please remove it before installing the MetaSound version.

Transform your game's audio capabilities with a comprehensive system for dynamic audio processing, featuring runtime importing, streaming, transcoding, exporting, and real-time microphone capture. From loading diverse audio formats to managing live microphone input, transcoding between formats, and precise audio control - handle all your runtime audio needs with a single solution.
