Loudness Penalty 2 Upgrade: Streaming Loudness Meter Plugin by MeterPlugs

The plugin reports realtime Loudness Penalty scores so you can see how online services will adjust your level before you upload. The block view displays max true peak, integrated loudness and loudness range together, and in Preview mode it shows how each service's gain change affects the overall loudness picture.

Spotify Loud mode uses a limiter to prevent clipping on quieter songs. Loudness Penalty 2 emulates that limiter in Preview mode and shows the gain reduction in real time. A delta button lets you hear only the material being removed.

The lock button freezes measurements, so scores do not drift after you have measured a track.

The interface is fully resizable. Drag a corner to resize it, or choose a preset from the size dropdown in the header. The compact list view reduces the plugin to a single column that can sit beside a busy session while still showing the key numbers.

In Pro Tools, the plugin processes faster than realtime within the Audio Suite, which helps when you are checking several tracks or revisions.
