WebPack loader to normalize audio loudness according to ebuR128

It requires ffmpeg to be installed

Install

``
npm i normalize-audio-loudness-loader
`

Use

In the WebPack config, add the loader for the audio files you want normalized:

`
{
test: /\.mp3$/,
use: [
{
loader: require.resolve('file-loader'),
},
{
loader: "normalize-audio-loudness-loader",
options: {
targetLoudness: -14,
}
},
],
},
`

Note that the loader gets an audio file and outputs the wav directly without emitting files. It is intended to be used with other loaders that write the audio and emit it. (such as the file-loader)

Configuration

You can set 3 values:

* `targetLoudness`: The target loudness (default: -23)
* `lra`: Loudness range (default: 7)
* `tp``: True peak (default: -2)
