A utility for batch-normalizing audio using ffmpeg.

This program normalizes media files to a certain loudness level using the EBU R128 loudness normalization procedure. It can also perform RMS-based normalization (where the mean is lifted or attenuated), or peak normalization to a certain target level.

## ✨ Features

- EBU R128 loudness normalization

- RMS-based normalization

- Peak normalization

- Video file support

- Docker support

- Python API

## 🚀 Quick Start

1. Install a recent version of [ffmpeg](https://ffmpeg.org/download.html)

2. Run `pip3 install ffmpeg-normalize`

3. Run `ffmpeg-normalize /path/to/your/file.mp4`

4. Done! 🎧 (the normalized file will be called `normalized/file.mkv`)
