LOUDNESS METERING AND LOUDNESS NORMALIZATION AT YOUR HAND

In the past, the usual way of controlling the level of the broadcasted audio materials was by counting samples. Today, the focus is put on the listener himself, more precisely on the listener’s audio perception and how he perceives the audio material’s loudness.

In order to support this revolution in the audio world, a number of international broadcast standards have been developed (BS-1770, EBU R128, ATSC A/85, etc.), based on perception tests and research. A major inconvenience when watching TV is adjusting the volume every time you switch channels or during the commercial breaks. Now, we have a solid foundation that helps us solve the problem of loudness oscillations of the audio materials, meaning that you don’t have to reach for the remote control.

The challenge is to mix correctly all kind of audio materials without losing the option to change the loudness level according to your artistic needs. This is possible only if you know the values of loudness descriptors every time you do your mix. In this way, your mix will be done according to human perception needs and you will not have any problem when it will be broadcasted.

For solving the loudness problem, we created a set of tools based on loudness standards specification, so that you can have a panoramic view of all the principal loudness descriptors, anytime you need. In other words, we offer you complete loudness measurements and the possibility to do a correct loudness normalization according to your own custom specifications and needs.
