mLoudness

A simple tool for normalizing audio files.
mLoudness provides a practical way to balance the volume of your sound files using industry-standard loudness algorithms like EBU R128. It is built to do one thing quietly and well, leaving you more time to focus on your work.

Features

• Multiple Standards: Fully supports Auto Normalize, Integrated (LUFS), Short-term, Momentary, RMS, and Peak normalization modes.
• Batch Application: Select multiple files or entire folders (WAV, FLAC, MP3, OGG, M4A, AAC, AIFF, WMA) and process them all at once.
• Rule-based Processing: Automatically route different sounds to different loudness targets based on file name prefixes (e.g., sfx_ vs mus_).
• Workflow Presets: Instantly load settings tailored for indie games, podcasts, YouTube, audiobooks, and more.
• Non-destructive: Processing runs safely in the background. The originals are never modified, with outputs placed neatly into a new normalized/ folder.
• Lightweight: Designed to use minimal space and resources.

How to use

1. Place your audio files into the application.
2. Select your normalization rules or load a preset.
3. Processing begins immediately in the background.
