Program Loudness Report

The program loudness report tab is used to display audio levels of digital content. MIP compares the program to a user defined reference value. If a violation occurs MIP turns that portion of the graph red. The info image icon provides more information about each of the reporting options.

Use the Search feature to select the channel/program of interest, loudness settings and report timeframe. MIP supports several loudness monitoring methods. Once the method is selected additional fields are displayed.
