🎧 Audio loudness normalization with ffmpeg.
npm install ffmpeg-normalize
const normalize = require('ffmpeg-normalize');
normalize({
input: 'input.mp4',
output: 'output.mp4',
loudness: {
normalization: 'ebuR128',
target:
{
input_i: -23,
input_lra: 7.0,
input_tp: -2.0
}
},
verbose: true
})
.then(normalized => {
// Normalized
})
.catch(error => {
// Some error happened
});
Parameters:
- input
- output
- loudness
- verbose
Type: string
Required: true
Path to the input file.
Type: string

Type: object
Required: true
Describes a target loudness.
Type: boolean

Type: string
Required: true
Options: ebuR128
(Experimental rms
|| peak
)
The normalization method to use. The ebu R128 normalization uses a two pass method to measure the original values of the input file. The other normalization methods only need the input_i value set.

rms and peak normalization (Experimental)
Min: -99
Max: 0
Default: -23
The normalization target level in dB/LUFS.
