TC Electronic updates Loudness Meter Range to comply with ITU-R BS.1770-2

TC Electronic has announced it has updated its entire Loudness Meter Range to comply with ITU-R BS.1770-2.

TC Electronic Loudness Meter Range

A global audio revolution is in the happening. For the past two years, pro audio and broadcasting has been moving away from peak level normalization and towards new, loudness-based solutions. In April 2011, another important step was taken when ITU-R upgraded its BS.1770 standard to BS.1770-2.

The first version of BS.1770 relied on ambiguous speech detection, which can have unexpected consequences trying to control the level of commercials or programs of certain genres. The improved 1770-2 recommendation incorporates a clever relative gate, making the measurement well-defined and practical to use, also across genres.

It is now even relevant for controlling the level of promos and commercials. Further, the new version is completely open standard, because TC Electronic donated core technology to EBU, where it was refined by PLOUD; and now brought back into the revised ITU standard.

Now, TC Electronic updates its radar loudness meters in System 6000 MKII (v. 5.11), DB4 (v. 3.20), DB8 (v. 3.20), DB4 MKII (v. 3.20), DB8 MKII (v. 3.20), LM2 (v.1.11), TC TouchMonitor TM7 & TM9 (v. 1.14) and for ProTools HD (LM5D version 2) to comply with BS.1770-2.

Besides from BS.1770-2 measurement compatibility, these machines also have dedicated EBU R128, TR-B32 and ATSC A/85 metering presets. Additionally, smooth and BS.1770-2 compliant loudness correction is now available in DB4, DB8, DB4 MKII and DB8 MKII, while DB2 will get the capability this summer.

The updates are available to download now.

TC Electronic LM2, Precision Loudness and True-Peak Meter

TC Electronic has announced the LM2, a precision loudness and true-peak level meter.

With LM2, you get a full-featured stereo loudness and true-peak level meter which is perfect not only for post, film and live production, but also for broadcast ingest, linking and transmission.

When you need to comply with broadcast standards, the numbers are paramount, and on LM2’s front panel, you can check the all-important digits instantly. For even more loudness details, simply connect LM2 to a PC or Mac via USB and you get full, realtime Radar screen picture using the included Icon application.

In short, with LM2 we stay true to our pioneering obligations and are proud to present you with next generation metering!

TC Electronic LM2 features

  • Precision Normalization and Meta Data — Global broadcast guidelines now recognize the need for keeping audio transmission easy and predictable; the main facilitators being transparent normalization and fixed metadata. LM2 facilitates precision normalization and optimum use of dialnorm metadata in AC3 transmission in order to avoid level jumps between regular programming and promos or commercials.
  • Standard Support — LM2 comes pre-loaded with factory presets compliant with new ITU-R BS.1770, ATSC A/85, EBU R128, NABJ, OP-59, BCAP and more guidelines. LM2 is easily field upgradeable* and will keep synchronized with global practices as they refine. Undoubtedly, standards will be updated within LM2′s warranty period which is a whopping 5 years.
  • Connections — LM2 always offers a wide variety of 24 bit resolution audio inputs and outputs: AES/EBU, TOS, SPDIF / AES3 id, ADAT and Analog. Analog I/Os are scaled in the analog domain for max utilization of converter dynamic range. Analog inputs may be trimmed at 0.01 dB precision. LM2 may connect via USB to a PC or a Mac for access to the Radar display, Logging, Remote control, Preset management etc.
  • 24/7 Logging — As a standard feature, LM2 comes with hindsight: The radar can show the past 24 hours, but LM2 actually includes so much memory of its own that you can take a detailed look one week back in time, even if it has had no connection to a computer. Dump log files routinely to a PC or to a Mac, import files into graphing templates included, or design your own in Excel, Numbers etc.
  • Ingest Normalization — The primary application for LM2 is as a loudness meter but it does one more thing very well: Automatic level offset of programs at a no-compromise resolution (48 bit, fixed point). LM2 therefore includes a precison true-peak limiter to avoid output overload when positive gain normalization is required. For fans of speech normalization, allow LM2 to measure some regular dialog and normalize to that. Otherwise, let its relative gate function automatically take care of all sources. Presets are included, the choice is yours.

# 10 Myths About Normalization – The process of normalization often confuses newcomers to digital audio production.

The word itself, “normalize,” has various meanings, and this certainly contributes to the confusion. However, beginners and experts alike are also tripped up by the myths and misinformation that abound on the topic.

# Free Mario Paint Composer for Windows and Mac; Mario Does John Cage – Hidden as an extra, Mario Paint Composer was one of the first software creations to meld music creation with game. It’s been a novelty favorite among 8-bit fans — not really a serious tool, but a curiosity nonetheless. But that requires a copy of Mario Paint. Now you can get the Mario-infected goodness on your Mac or Windows machine, free.
