July 25 2016, 03:10
RTW will be showcasing its full range of audio monitoring and metering software and hardware devices, as well as a few new product updates at IBC 2016 in Amsterdam (Stand 8.D89). Its new audio processor hardware, APRO-CLC01 for Continuous Loudness Control (CLC), will be shown for the first time in Amsterdam. The German company is also showing new upgrades for both its Loudness Tools and Mastering Tools PlugIns.

The combination APRO-CLC01 provides the first OEM hardware for the CLC algorithm that RTW developed in cooperation with the German Institut für Rundfunktechnik (IRT). The CLC signal processing algorithm allows users to constantly control and regulate to a given program-loudness value and definable loudness range with minimal obstacles for unknown, live content.

“At RTW, we are constantly thinking of new ways to improve our technology and provide our international customer base with innovative products,” says Andreas Tweitmann, CEO of RTW. “We have received a positive response to our CLC technology, and the input we gathered from customers helped us look into ways to further improve the software.”

RTW also announced that a new software version 4.0 is available for its Loudness Tools and Mastering Tools software. The new version adds support for Mac OS X 10.11 “El Capitan” and addresses user requests with features like a selectable 12th octave RTA, the implementation of cinema loudness standards (TASA and SAWA), and a freely scalable display. Also now with version 4.0, Loudness Tools and Mastering Tools software can operated as stand-alone versions on both Mac and PC.

“The new software updates for our Masterclass PlugIns range were designed to provide our users more options to adapt our comprehensive and easy-to-use audio monitoring solutions to the way they like to work,” explains Andreas Tweitmann, CEO, RTW. “The upgrade to version 4.0 makes our Masterclass PlugIns compatible with more operating systems and increases the functionality for all audio professionals that need to meet certain loudness standards and are concerned about noise control.”

Loudness Tools and Mastering Tools are part of RTW’s Masterclass PlugIns range that provides RTW hardware meters as software. By transferring the analyzer tools to plug-ins that require no additional hardware, RTW has made its tools more available to musicians, radio producers and audio/video engineers who need to meet loudness specifications required by TV and radio broadcasters.

Loudness Tools features metering and loudness displays for mono, stereo, multichannel and surround applications (eight channels max.) All standard sampling rates up to 96 kHz, including all widely used PPM and TruePeak measurements and scales, are also incorporated into the software. Mastering Tools consists of extensive analysis and display functions for mastering, metering and loudness measurements from single-channel up to multichannel applications. These include a wide range of PPM scales and displays, VU appearance, TruePPM measurements, vectorscope, Surround Sound Analyzer and RTA.  

In addition, RTW will exhibit the new software version 1.5 now available for TM3-Primus and USB Connect. Version 1.5 adds support for Mac OS X 10.11 “El Capitan” and adheres to the recently released standard changes in the EBU Loudness Recommendation (EBU R 128). Users can now select to read the Smax and Mmax values. Momentary or a maximum Short-term loudness measurement is a parameter to characterize and control the loudness of commercials, promos, etc. RTW offers both functions as a freely selectable feature. Users may turn both measurements on or off, depending on what their work entails.

RTW will also showcase its TouchMonitor instruments and SurroundControl series, created to help comply with all major industry loudness standards. The SurroundControl 31900 and 31960 series products are designed for controlling, analyzing and monitoring stereo, surround sound and multi-channel programs. The SurroundControl 31900 offers a full range of audio and signal analyzing tools, while the 31960 incorporates these tools specifically for television and video studio applications.
