Audio normalization script for Python/ffmpeg
This program normalizes media files to a certain LUFS 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.
Install Python (2.7 or 3.x), then install the program with:
pip install ffmpeg-normalize
