It can be seen that the upmix is only available in one upmix configuration for the 2-channel ALC. It is not possible to
use the upmix in PASS, AutoMAX-II or Follow Metadata Path configuration.
ALC Filter
The ALC filter parameter sets the type of filtering applied to the audio content by the ALC to measure the audio
loudness
• The ITU-R BS.1770 mode (factory) is the most common way to measure loudness, given in LKFS units.
• The Jünger Level mode is a Jünger proprietary peak operating level control, given in dBFS units.
