NLC 5.1: Surround Sound Loudness Control

Neural Loudness Control multi-channel, surround sound processing.

Neural Loudness Control: Control the loudness, don't squash it.

Neural Loudness Control (NLC) 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.

NLC actually mimics human perception of audio and provides tight control of loudness. Neural's Loudness Measurement detects spectral and density differences, inter-channel relationships and temporal overlaps within the audio signal. After detection, NLC applies the appropriate gain or attenuation to the audio to achieve a user-defined loudness level.

If NLC is used ahead of an AC3 (Dolby Digital) transmission, the target loudness level will also match the DialNorm metadata information, thus providing viewers with a consistent audio experience.

Key Benefits of Neural Loudness Control

• 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 look-ahead technology, makes large gain corrections imperceptible
