Grass Valley Loudness Control

Automatic Loudness Control (ALC)
Advanced Loudness Control Solutions Which Prevent Excessive Audio Jumps
Excessive loudness variation is probably the most common viewer complaint, and it's now something you can eliminate entirely. Our automatic loudness control solutions for our Densité interfaces are designed to address all typical loudness problems, including audio jumps between programs and commercials, without adversely impacting the program content.
Uniquely, Grass Valley offers two distinct automatic loudness control solutions which bring together the very best loudness technologies:
  • ALC with Linear Acoustic AEROMAX processing
  • ALC with Grass Valley wideband audio processing
Both solutions can be used effectively to address loudness problems across multiple applications, such as broadcast playout, server ingest, production and post-production. However, the best fit solution will depend on an individual facility's particular channel mix and program dynamics, as well as the associated playout workflow and equipment.

Multiprogram IP Transport Stream Loudness Processor
AXINO is an EBU R128 and A/85 loudness monitoring device that can effectively identify potential loudness variations directly from compressed TV channels. The embedded loudness analyzer eases the review process of potential loudness excursions and helps quickly identify and report loudness problems. When faulty channels are identified, the internal real-time loudness processor can be selectively enabled to correct both channel-to-channel and program-to-interstitial loudness issues. For instance, the built-in automatic loudness control (ALC) can eliminate excessive loud commercial advertisements.

High-Quality Video and Loudness Monitoring with 3G/HD/SD SDI to HDMI Conversion
Kaleido-Solo is a compact, standalone 3G/HD/SD SDI video to HDMI converter that enables the use of low-cost LCD displays for video and loudness/dialnorm monitoring. Ideal for many professional monitoring applications, including production, mobile truck, post-production and broadcast, Kaleido-Solo eliminates the cost and complexity of a traditional loudness monitoring device.
