A loudness log is a report of the loudness of an audio file and it allows you to provide documentation that your files adhere to loudness standards.
The log provides data about an audio file's momentary loudness, short-term loudness, integrated (overall) loudness, and loudness range. You can use these values when mastering for broadcast to ensure compliance with loudness standards (such as the CALM Act).
Select the data you want to analyze.
If no data is selected, the entire file is analyzed.
Choose Tools > Generate Loudness Log.
The loudness log is created using the same folder and base name as your sound file with _loud.txt appended to the name.
The log will record the file name, format, loudness metering mode, and loudness values throughout the selection or file.
The log will be automatically opened in your default text editor.
Select the Enable surround processing on 5.1 media check box on the Advanced tab of the Loudness Meters if you want to treat audio with six channels as surround audio when measuring loudness (a gain of ~1.5 dB is applied to the left and right surround channels). When the check box is cleared, all channels contribute equally to the loudness measurement.
