Final Check Meter
Final Check is a tool developed by Merging Technologies for monitoring audio levels. In its VCube implementa-
tion, it focuses mainly on the loudness measurements defined by the EBU R-128 recommendation.
The output of Final Check Meter is an XML report file in the same directory as the wrapped file. This file will include
measurements of
integrated , momentary and short-term loudness values, as well as the loudness range and
the maximum true peak . All these measurements may be checked against the recommendations, delivery
requirements or local regulations in force regarding loudness.
When Level Magic™ is combined with Final Check Meter , the measurments are made on the output of Level
Magic™, so that the measurements are always consisitent with the content of the wrapped file.

Report Files
A Final Check report file will look something like this when opened in Notepad or a text editor:
<?xml version="1.0" encoding="UTF-8"?> XML information
