Loudness Insight
EBU R128 Compliant Browser-Based Loudness Analyzer
Overview
Loudness Insight is a web application that analyzes the loudness of audio files directly in the browser, powered by the Web Audio API and FFmpeg (WebAssembly).
Key Features
- Client-side Analysis: Securely and rapidly analyzes audio locally using WASM, meaning files are never uploaded to a server.
- Detailed Loudness Visualization: Clearly displays professional audio metrics such as Integrated Loudness (LUFS) and True Peak.
- Broad Format Support: Supports a massive variety of audio file formats thanks to FFmpeg's robust decoding capabilities.
