I was recently mixing some tracks and needed to compare their loudness with commercial songs. Since these will be released on streaming platforms (Spotify, YouTube, etc.), I often checked the loudness penalty scores of my mixes on loudnesspenalty.com.
Unfortunately, that site only shows the penalty for one song at a time — so I decided to build something similar myself, with a few extra features I wanted.
You can check it out here:

Features added:
- Calculate loudness values for multiple tracks
- Jump to the same position on different tracks when played (useful for comparing multiple mixes of a song)
- “Installable” as a PWA on PC and works offline
- Keyboard shortcuts, and a few other small touches...
I’m sure there’s existing software that can do similar things, but I improved my web dev skills through this project — so I thought I’d share it anyway.
Maybe someone will find it useful
