The Audio Loudness scope provides a real-time calculation of the program loudness for the preview player.
The meter displays 6 metrics as defined in EBU-R128.
These metrics include:
- Momentary loudness
- Short term loudness
- Integrated loudness
- Loudness range
- Peak
- True peak
The display can be customized by clicking on the hamburger menu to disable the display of specific meters.
The meter readings could become inaccurate if the user seeks around the timeline. To get accurate readings for a segment of a clip or timeline, follow these steps:
- Seek to the position that you want to begin measurement
- Click the “Reset” button in the Audio Loudness scope
- Click “Play” in the player.
- Observe the Momentary, Short Term, Peak and True Peak values while the player plays (these are dynamic metrics that change over time)
- When the player reaches the position where you want to stop, click pause
- Observe the Integrated loudness and Loudness range. These values apply for the duration of the segment that was played.
