Advanced runtime audio processing for Unreal Engine. Import, stream, transcode, and manipulate audio at runtime across all platforms - with full Blueprint and C++ support.
A comprehensive solution for dynamic audio processing - from loading files and streaming live data, to microphone capture and voice activity detection - all without leaving Unreal Engine.
Load audio from files or memory buffers at runtime. Export to multiple formats with sample rate and channel control.
Dynamic audio buffer management for continuous data streaming from any source, including network audio and TTS.
Real-time audio capture with automatic platform permissions, voice activity detection, and speech boundary events.
Convert between audio formats dynamically with full control over quality, sample rate, and channel count.
Runtime Audio Importer integrates seamlessly with Unreal Engine's native audio system - imported sound waves behave exactly like built-in sound waves across all supported platforms.
File path, URL, memory buffer, microphone, or any PCM provider
On-device decoding with optional resampling, channel mixing, and format conversion
A native-compatible UE sound wave ready for any standard playback workflow
Full playback control with time tracking, PCM callbacks, and completion events
Four distinct sound wave types to cover every runtime audio use case.
Runtime-imported audio from files or memory buffers, with full playback control. Supports MP3, WAV, FLAC, OGG, BINK, and RAW PCM.
Dynamic buffer management for continuous audio streams - ideal for TTS output, network audio, or any incremental PCM source.
Real-time microphone capture with automatic platform permissions, voice activity detection, and speech start/end events.
Capture audio directly from Pixel Streaming clients microphones. Supports both Pixel Streaming and Pixel Streaming 2 architectures, including multi-player scenarios.
Broad format coverage and first-class support for every major platform Unreal Engine targets.
Beyond importing, the plugin provides comprehensive playback management, real-time PCM access, metadata inspection, and advanced audio manipulation - all from Blueprints or C++.
Play, pause, stop, and rewind with precise time tracking. Monitor playback position and percentage, bind to completion events, and manage audio memory manually.
Access raw 32-bit float PCM data as audio plays via callbacks. Ideal for audio visualizers, frequency analyzers, and custom DSP effects.
Inspect audio files without fully importing them - retrieve duration, sample rate, channel count, and format without the overhead of full decoding.
Adjust volume, pitch, looping, and virtualization mode at runtime. Resample and mix channels, set initial desired sample rate and channel count.
Precise speech boundary detection with configurable silence duration and minimum speech thresholds. Bind to speech started and ended events.
Create duplicates with shared audio buffers for parallel playback, layered effects, and resource-efficient audio management.
