Neural Loudness Control Options on APM6801
+
Neural Loudness Control is available on its own, and in various combinatiosn
with other audio processing options. The following Neural Loudness Control
options are available on APM6801
+
:
•

D Neural Loudness Control for 2.0 or 5.1
This module receives 2.0 or 5.1 input, and outputs audio in the same format.
It can do one or the other, not both.

D Neural Loudness Control for 2.0 and 5.1
The Neural Loudness Control 6+2 configuration is used when a 5.1
multichannel or surround sound mix is accompanied by an independent
stereo mix. It uses the same advanced psychoacoustic and signal processing
techniques to accurately detect and regulate the perceived loudness of stereo
and 5.1 sources. Common uses are for network programming with SAP,
LtRt or Descriptive Video programming.
