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.
