Miranda Axino 300x180At IBC in September, Miranda will be highlighting a loudness monitoring and correction processor for high program count IP transport streams. Called Axino, it's intended to address loudness control regulations around the world, including the Calm Act in the United States.

A single Axino processor is designed to provide continuous monitoring and selective loudness correction across hundreds of programs within an MPEG IP transport stream. The loudness monitoring and logging is performed using BT. 1770 and EBU standards, and the loudness control is designed to address excessive segment-to-segment and program-to-program loudness.

Whenever any program is excessively loud, the problematic signal is logged and automatically put on a watch list. If this excessive loudness persists, the service provider can alert the content provider and request a correction to the program. If the problem is not resolved by the content provider, the service provider can activate the Axino's loudness correction to bring the problematic program back within range. The processor uses Miranda's Automatic Loudness Control, through which AC-3 audio is decoded from an IP stream for real-time loudness measurement and correction. After processing, the audio is reinserted back to its original location.
