Principles of Operation
The AERO.mobile is built on the foundation of the AERO.one and provides the same in-
tegrating long-term loudness controller, multiband short-term loudness controllers, LtRt
or LoRo downmix, metadata input for channel and processing control, plus GPI control
of switching functions. However, new Mobilizer technology has been added to provide a
psychoacoustic boost to specific audio characteristics critical for intelligibility under ad-
verse listening conditions such as small speakers and/or noisy environments.
Specific processing presets and adjustments are discussed in Chapter 5.
Figure 1-1 shows the internal audio path of the AERO.mobile. It should be noted that this
diagram is a general representation of signal flow and shows the optional Dolby Pulse (HE
AAC) encoder. Please consult the appropriate section of this manual for specific function-
ality.
