The integrated loudness measurement is always on, for all outputs, once the GUI App starts. To comply with the ITU
standard, the signal's loudness must be greater than -70 LUFS before an integrated measurement is registered. From
hereon, the reading will continue to update over time and represents the average loudness of the output since the start.
The integrated loudness measurement for all outputs can be reset by touching the LUFS value (on any meter) for more than
one second.
