Every day, millions of people around the world adjust their volume controls over and over again. Why? Because of the most fundamental audio issue of all - the control of loudness.

More Than Peaks
Rather than just measuring peak levels, LM6 allows you to use a much more audio-friendly method when delivering audio for CD, MP3, AAC, AC3, broadcast or cinema. Further, it is fully compatible with 'dialnorm' in Dolby AC3, which makes the codec perform much better and more predictably than with any measurement based on just peak or dialog levels.

In short, with the LM6 algorithm, you get an extremely transparent signal path regardless of audio format - from mono to 5.1 surround sound.

Radar Control
The detailed radar meter is the perfect tool for measuring and monitoring your audio during production, mixing and mastering, and it ensures absolute compliance with broadcast, post or cinema delivery specifications.

Formats and Compatibility
LM6 is part of the universal, standardized loudness control concept (compliant with ITU BS.1770-3, EBU R128, ATSC A/85, TR-B32, etc.), whereby audio can be easily measured and controlled at any given stage of production or distribution. Further, LM6 is compatible with any other piece of equipment that meets the same universal standard.

A quantum Leap

LM6 represents a quantum leap away from simply measuring audio level to measuring perceived loudness. The old level method is responsible for unacceptable level jumps in television, for music CDs getting increasingly distorted, and for different audio formats and program genres becoming incompatible: Pristine music tracks from the past don't co-exist with new recordings, TV commercials don't fit drama, classical music or film and broadcast doesn't match. The most fundamental audio issue of all - control of loudness - every day makes millions of people adjust the volume control over and over again.

LM6 is part of a universal and ITU standardized loudness control concept, whereby audio may easily and consistently be measured and controlled at various stages of production and distribution. LM6 works coherently together with other TC equipment, or with equipment of other brands adhering to the same global standard. Follow the guidelines given to allow audio produced for different purposes to be mixed, without low dynamic range material such as commercials or pop CD's always emerging the loudest.

 

  • Realtime loudness meter compliant with EBU R128, ATSC A/85, TR-B32 and ITU-R BS.1770-3. For legacy purposes, LM6 can also be switched to the ungated, original BS.1770 measure of Program Loudness..
  • Loudness History Radar display.
  • True-peak Bargraph display.
  • Supports mono, stereo and 5.1.
  • Presets for use in Broadcast, Music, Post and Film.

 

Loudness meters in MKII frames feature 24/7 logging capability without even seeing a computer. Measurement and logging presets are found in the Metering factory preset bank.

Loudness Website

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.

The site is an answer to the highly relevant question:
"What Is Loudness, and Why Is It Important?"

In the Press

There's a reason that world-leading broadcast magazine regularly invite us to share our knowledge: we've been pioneers in the digital audio world since 1985.

We've taken part in research studies and the definition of international broadcast standards right from the start, donating technology which has become a crucial part in new, open international standards.
