Description
Version 2.0 is out!!
A new offline rendering engine up to 200x faster than real time, and rebuilt fully native in C++ and Slate. Details under New in 2.0.
Consistent loudness across hundreds of assets, in one pass.
Audio Normalizer measures your Unreal audio with industry-standard BS.1770-5 K-weighted LUFS metering and brings every asset to your target. Procedural sources are rendered offline with their random logic intact and averaged across variations, so MetaSounds and Sound Cues get a real reading, not a guess.
Features
BS.1770-5 integrated LUFS metering with true K-weighting derived per sample rate
True peak, 4x oversampled
Sound Waves, Sound Cues and MetaSounds, with per-type filters and Select All
Offline rendering engine, up to 200x faster than real time
MetaSounds rendered with their random logic intact and averaged across variations; Sound Cues rendered through their full graph
Low, Mid and High presets or custom LUFS and true-peak targets, with a tolerance to skip assets already in range
Analyze, preview every asset's current and target loudness, then apply
Every gain change re-rendered and re-measured before it is kept, rolled back if it is off
The whole batch applied as one Unreal undo step
Non-modal: keep working in the editor while it runs
Text, CSV and filtered-assets reports, one switch each
Blueprint API for analysis and normalization, synchronous and asynchronous
Native Unreal window: Enter runs, Escape cancels
New in 2.0
Offline rendering, up to 200x faster than real time. Analysis no longer waits for the sound to play. Large batches finish in seconds.
Fully native C++ and Slate. Rebuilt on the engine's own code and widgets: instant startup, engine-native look, and fast moves to each new engine version.
BS.1770-5 metering with true K-weighting. The filter is derived for each file's own sample rate, and the implementation is checked against FFmpeg's ebur128.
True peak. 4x oversampled true-peak measurement replaces sample peak.
Verified gains. Every change is re-rendered and re-measured before it is kept. If the result is off, it is rolled back. No more accidental +80 dB.
Preview, then apply, then undo. See every asset before anything changes, apply as one undo step, undo as one step.
Reports. Text, CSV and a filtered-assets report.
