The silent death...

Hi folks.

Do you sometimes have the feeling, of not feeling comfortable the way you handle and administrate your valuable music ( and video and image) collection?

You don't really know -- if all the audio file integrity is still given  (after all those years of moving files here and there) !?!?

Loundess war - finally over ???

Hi folks.

Anybody heard about EBU R128??

To be honest. I didn't until recencly.

I accidently stepped  over EBU R128 (EBU=European Broadcasting Union, R128=Recommendation 128) while looking for a better ReplayGain solution.

R128 finally defines a standard how loudness should be measured and applied in an acceptable way.

The standard was based on  ITU BS.1770 ( International Telecommunications Union) released in 2006.
ITU BS.1770  has been widely applied in the broadcasting scene.
EBU R128  significantly enhanced that standard by a function called gating (You'll learn more about it later on.)  The original ITU BS.1770 has been updated to ITU BS.1770-3 by now and includes the gating function as proposed by EBU R128.

Not only us - audio geeks - have a huge problem with low quality music and messup of audio data due to "Loudness War" - NO - broadcasters face the same challenge on a daily basis.  They can not sit down and change the volume on every piece they are broadcasting.

They have to normalize audio of much more media sources, such as speach, film, commercials, podcasts, audio asf. And by doing so, they're compressing and messing with  the audio data even further.
