  • Stats and Logging - Peace of Mind when Delivering for Broadcast

Compatibility

LM6 Radar Loudness Meter is available in Audio Units, VST, AAX, AudioSuite and RTAS plug-in formats. No additional hardware such as Pro Tools TDM or PowerCore is needed - all you need is an iLok2 USB Key for holding the plug-in license.

In short, you can use LM6 with hosts such as Media Composer, Final Cut Pro X, Pro Tools, Logic Pro, Nuendo, Wavelab, Sequoia, etc. on a Mac or PC and whether your productions are in mono, stereo or 5.1.

Always On

Because LM6 is designed for demanding hosts such as Final Cut Pro and Media Composer, we have paid special attention to 'sleeping beauty' functionality.

Therefore, it works great even in environments restricted by screen space or by CPU resources. In other words, you can leave it on at all times for a quick overview without compromising computer performance.

Universal Descriptors

LM6 features two Universal Descriptors, by which the entire loudness 'landscape' of a program, film or music track can be precisely characterized.

The left descriptor shows Loudness Range (LRA) which measures the average distance between soft and loud parts in your program material in LU.

The right descriptor shows the all-important Program Loudness parameter.  Depending on which broadcast standard you have to conform to, there is a certain target level that you must not exceed - and Program Loudness reflects that number in LUFS or LKFS.

You can also decide to have these descriptors diplay other parameters such as 'max loudness' or 'sliding loudness'.

Offline Measuring

If you use it in Pro Tools as an Audio Suite plug-in, you can even benefit from the off-line function and measure the loudness of your audio faster than real time.

Below, you can see how off-line measuring works with AudioSuite. Note how the tracks get measured much faster than real time and how the radar display reflects the overall loudness landscape almost instantly.

Also, even in offline mode, a log file of the measurement results is created for your documenting needs.

User Interface

Main
Presets and main parameters such as descriptor settings (e.g. Loudness Range, Program Loudness, Sliding Loudness, Loudness Max, etc.) are found on the Main Page.

You can also define whether you want to display LUFS or LKFS. The two parameter values are in fact identical, but some standards prefer the use of LUFS (such as EBU R128), while others prefer LKFS (auch as ATSC A/85).

Setup
You will find detailed parameters on the Setup Page. For instance, you can define the destination of the logging file and adjust the Peak Indicator. 

Further, you can set details about how the Radar should operate. The speed of the radar is adjustable between 1 minute and 24 hours. This would also be the place to set the Momentary Loudness Range.  

Stats
Gain a complete statistical overview on this page. LM6 keeps track of detailed stats that you can save to a standard formatted text file for documentation and evaluation. 

Radar
Loudness History, Momentary Loudness, True-peak Level and flexible descriptors are combined to give you the ultimate loudness overview in a single view.

Crossing Platforms

The user interface of LM6 is similar to other TC Radar Loudness Meters found in LM2, TouchMonitors, System 6000, DB4 & DB8 or LM5D.

So if you are already familiar with the radar, crossing platforms is seamless, and you are sure to always get the correct numbers - also when working in a DAW.

Loudness-Website

Es kann zur echten Herausforderung werden, bei allen Aspekten des komplexen Themas "Lautheit" den Überblick zu behalten. Daher haben wir eine spezielle Site zu diesem Thema publiziert. Hier finden Sie relevante Informationen zu den wichtigsten Aspekten.

Im Mittelpunkt steht dabei die Frage:
"Was ist Lautheit, und warum ist dieses Thema wichtig?"

Up to date in Sachen Standards

Bei der Entwicklung von Rundfunkstandards schenkt man uns Gehör und Vertrauen. Wir haben sogar vielen internationalen Organisationen jene Technologien überlassen, auf denen auch die Arbeit Ihres Senders beruht.

Rechtsvorschriften zur Lautheit im Rundfunk sind ein sich ständig weiterentwickelndes Feld. Aber ganz gleich, wo Sie senden und welche Loudness-Produkte von TC Electronic Sie verwenden: Wir unterstützen wir Sie bei der Einhaltung der jeweils aktuellen Rundfunkstandards, die Sie beim Sendebetrieb zu beachten haben.

Reviews

Mix
von Brandon Hickey

The most dazzling feature of the LM6 is the large “radar” meter that performs a revolving wipe, showing average loudness over a long duration. It can be set to span as short as a minute or as long as a day. The decibel resolution can be adjusted to cater to the needs of the particular project. Certainly, watching trends and deviations in this way rivals any other system yet devised for long-term loudness metering, especially when referencing the meter during tracking situations. Rather than looking back and forth between Pro Tools waveforms and the plug-in, the radar’s interpretation of the waveform paints a clear enough and meaningful picture on its own.

Music Connection
von Barry Rudolph

TC Electronic has been on the forefront of doing the science, developing standards and designing a long line of hardware tools to measure accurately, audio loudness over time. The LM6 Radar Loudness Meter plug-in, now for any DAW platform PC or Mac, displays true-peak warnings and true-peak bar graphs and conforms to all major broadcast standards. LM6 measures up to 5.1 channels of audio program loudness and provides a graphical histogram of their dynamic range over a pre-determined time period from 1 minute to 24-hours. In Pro Tools 10, I use the AAX version of the LM6 plug-in across my stereo bus to track and locate peaks (overs) when mixing music.
