ffmpeg-normalize

PyPI version Docker Image Version GitHub Actions Workflow Status

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.

Batch processing of several input files is possible, including video files.

Quick Start

  1. Install a recent version of ffmpeg
  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)
