Signal Histogram panel

1. Y axis. Units are percent-

ages.

2. X axis. Units are full-

scale loudness.

3. Histogram traces.
4. Segment key.

The Signal Histogram panel summarizes loudness measurements for
programming segments selected using the Readings Timeline panel
(p. 40). The display updates as you add or remove segments from the
timeline, or adjust their limits.

Bars of the histogram represent the proportion of readings in 1 dB inter-
vals, arranged along the X axis of the histogram from lowest measured
loudness to highest. The height of a bar is the percentage of the read-
ings in its interval.
