Loudness is known and is not compliant – Processor is forced into fixed gain normalisation with True Peak limiting Loudness is not known at all – Processor is forced into full dynamic loudness control with True Peak limiting encoder is the answer. This allows the target loudness to be dialled in and makes real time adjustments to keep it seamlessly inline whilst maintaining the highest possible audio quality. The ability to incorporate upmixing or downmixing and Dolby decoding and/or encoding is also available. However, a real time loudness manager in the chain like this should be used selectively and appropriately. All the good ones will allow for incorporation into playout automation systems whether through simple GPI contact closure commands, or through an HTTP based protocol. Typical usage scenarios would be: Loudness is known and is compliant - Processor is forced into bypass and content passes untouched. In addition, logging of all measured loudness values is available as an option. The Jünger approach is to provide a software application that runs on a host PC and allows a real time display of input vs. output loudness and/or true peak, along with the ability to create log files at pre-determined time intervals. Log files are stored in .csv format and an inbuilt log file analyser means that when re-called, the data values will be used to re-create the original plot for easy visualisation of historical loudness levels. A zoom function then allows precise analysis of suspected problematical date and time ranges.
