How Works

VoluMatch is a desktop app built with Python and Tkinter that allows users to normalize the perceived loudness (LUFS) and RMS of MP3 audio files. It provides a simple interface to load multiple songs, view their duration, RMS, and LUFS levels, and apply consistent loudness normalization using FFmpeg's loudnorm filter. The app preserves metadata, supports batch processing, and offers a progress bar and console log for feedback. It also includes customization options like setting a target LUFS and (optionally) activating dark mode for better visual comfort.
