Loudness measurement : despite progress, new tools are needed in order to get it right

Loudness measurement : despite progress, new tools are needed in order to get it right | Video Breakthroughs | Scoop.it

It has long been a challenge to achieve consistent sound levels that don't force listeners to readjust their set at every program junction. Today's multichannel world, with playout systems sequencing programs, commercials and trails, means there is no scope for manual adjustment of levels. Instead, volume management policies must be defined. The ITU BS.1770 measurement has been around for a few years and defines an algorithm for loudness measurement. However, it offers no guidance over the values that might offer suitable settings. This challenges manufacturers to keep up with an evolving set of measurement norms by allowing a significant number of user variables. Incorrect setting of these can cause major variations in the values displayed, and a thorough understanding of loudness is necessary to correctly configure a meter so that it gives the required measurements.

Miranda Launches End-To-End Loudness Monitoring, Logging and Correction Solutions at NAB [PR]

Miranda Launches End-To-End Loudness Monitoring, Logging and Correction Solutions at NAB [PR] | Video Breakthroughs | Scoop.it

Miranda Technologies Inc., a worldwide provider of infrastructure, playout and monitoring systems for the television broadcast, cable, satellite and IPTV industry, today announced the launch of its end-to-end loudness monitoring, logging and correction solutions for both automatic, real-time processing during playout and file-based pre-processing prior to air.

 

First, is the introduction of segment-aware loudness monitoring and logging to the Kaleido series multiviewers and the real-time loudness correction processors. Using Miranda's iControl system, broadcasters can now accurately log the average loudness per segment, enabling easy creation of detailed reports at a later date, thus enabling them to address loudness control regulations around the world, including the Calm Act in the USA.

 

Secondly, because the abundance of content, including most commercials, is now file-based, broadcasters can now monitor and correct content prior to playout, using Miranda's Enterprise Suite.

 

This file-based processing provides effective loudness correction while maintaining the full dynamic range of the original content.

Loudness Normalisation for web applications at NoTube

Loudness Normalisation for web applications at NoTube | Video Breakthroughs | Scoop.it

Presently, the audio playback of various streams from different sources causes quite often an annoying experience for the listeners. The reason behind that is that the loudness levels of these different streams can be completely different and do not match a comfortable listening experience on the end users’ devices.

 

Measurements in the past have shown that even similar audio streams which are broadcast via the broadcast network and simultaneously on the Web, e.g. Internet radio services, might have very different loudness levels. Even more different levels can be expected if various streams from completely different sources are collected to form a Rich Media Service.

 

Why was this of interest to NoTube?

 

In the NoTube platform, media coming from different sources are presented to the end user. This brings along a high risk of annoying loudness jumps, among others between news items that are provided by different broadcasters. The use of a loudness module in the NoTube platform could eliminate this effect by normalising the loudness levels.
