Belo selects MultiMerge-NLC for stereo-to-5.1 upmix

Belo has chosen the Harris Neural-THX Surround MultiMerge and Neural Loudness Control (NLC) advanced audio processing solution for its on-air chain to upmix stereo to 5.1 surround sound when necessary.

MultiMerge-NLC, a collaboration between Harris and Neural Audio, provides a loudness-controlled output that can eliminate annoying, drastic changes in volume, especially between programs and commercials.

MultiMerge-NLC combines the ability to transition in a seamless fashion between 2.0 stereo and 5.1 surround sound with a simultaneous 5.1 and 2.0 output. NLC answers the need of TV broadcasters and network operators to manage perceived loudness levels within a specific desired volume range.

Unlike traditional volume management solutions, this innovative solution uses Neural Audio’s perceptual loudness measurement tool to model how the human ear will perceive the loudness of the audio content.
