DTS Neural Loudness Control

Control the Loudness, don't squash it


DTS Neural Loudness Control (NLC) technology is an advanced loudness leveling technology that accurately measures and regulates the perceived loudness differences in audio. Annoying side-effects of traditional audio processing are eliminated and loudness is controlled without squashing the quality of the audio. The result is audio with a natural, open quality and a consistent audio experience for all viewers.

DTS NLC mimics human perception of audio and provides accurate control of loudness. DTS Neural Loudness Control detects spectral and density differences, inter-channel relationships and temporal overlaps within the audio signal. After loudness measurement, DTS Neural Loudness Control technology applies the appropriate gain or attenuation to the audio to achieve a user-defined loudness level.




If DTS Neural Loudness Control is used ahead of an AC3 (Dolby Digital) transmission, the target loudness level will be held consistent to the DialNorm metadata information, thus providing viewers with a consistent audio experience.

DTS Neural Loudness Control Key Features Include:

  • Guarantees a consistent viewer experience despite variations in consumers' equipment
  • Adheres to the ITU BS.1770 loudness recommendation, and--more importantly--agrees with your viewer's perception of loudness
  • Uses the same loudness control for stereo and 5.1 surround content
  • Manages loudness without a "squashed" or compressed sound
  • Corrects loudness while preserving the original equal loudness curve
  • Using predicting technology, makes large gain corrections imperceptible

Applications

DTV facilities, Production studios, Ingest Points, Mobile Production. Commonly used in front of STL paths, Dolby-E or AC-3 encoders.
