Overview: Before and After Loudness Processing
The Butterfly Meter™ displays your content pre and post loudness normalization - and it's an integrated part of the aNorm algorithm.
The innovative graph instantly gives you an overview of how and why the incoming audio is adjusted.
In other words, the sheer look of the meter is just as astonishing as it is intuitive and informative.

How to Read The Butterfly Meter
The color scheme of the Butterfly Meter is similar to our Radar Meter. Yellow represents loudness above the pre-defined target level and the green colors show loudness below the target. You can change the display scale to your preference in the settings. The example below has been set to 6 LUFS/LKFS steps.
A Match Made in Heaven
The Butterfly Meter is not meant as a substitute or a replacement for our legendary Radar Meter. In fact, the two complement each other perfectly as they are created for two very different tasks: the Radar Meter shows loudness history with critical details in a single view and the Butterfly Meter is your processing meter, focusing on loudness pre and post processing.
In the chart below, you can get an overview of the key differences between the Radar Meter and the Butterfly Meter.
In action the process is surprisingly transparent. I tried it with a variety of material, some quite challenging and I would have been happy to transmit everything I heard. The new Butterfly meter gives an intuitive overview of the audio pre and post loudness normalisation. aNorm running on a DB6 is a well executed answer to a problem that is or will be faced by most broadcasters.
Keeping You Up To Date
We have been listened to by those actively setting broadcast standards - we've even donated our technology to many of the same international bodies that impact your broadcast work.
Legislation on loudness in television is constantly evolving. However, regardless of your location and no matter which TC Electronic Loudness units you use, we will always help you remain compliant with the latest revision of the broadcast standard that impacts your work.
Defined by The International Telecommunication Union, the ITU BS.1770 recommendation is global and one of the most important broadcast standards as many other standards are based on it.
Our broadcast products supports all revisions of BS.1770, including the latest BS.1770-3.
The P/LOUD group, which is part of The European Broadcasting Union (EBU), has defined the R128 standard that applies to many European countries.
ATSC A/85 is specified by The Advanced Television Systems Committee (ATSC) and applies to US broadcasters. A/85 is rooted in BS.1770 Loudness and True-peak level and uses LKFS as loudness unit.
Defined by the Association of Radio and Television Businesses (ARIB), TR-B32 is a Japanese broadcast standard that builds on ITU BS.1770-2.
Keeping track of the multitude of issues around loudness can be a challenge. That's why we've created a one-stop dedicated loudness website where you'll find critical information on the most important issues.
