Audio Normalizer — open-source notice This tool distributes the unmodified single-thread @ffmpeg/core 0.12.10 JavaScript and WebAssembly files under the GNU General Public License, version 2 or any later version (GPL-2.0-or-later). The JavaScript file is audio-normalizer-core.js. The original Wasm bytes are distributed unchanged in four ordered files named audio-normalizer-core-001.bin through audio-normalizer-core-004.bin; joining them yields the exact published core Wasm SHA-256. The hashes, package declaration, and reproducible preparation step are recorded in the module's package metadata, tests, and tools/prepare-engine.js.
