NAB 2016: RTW launches new audio processor OEM hardware

RTW has used this year’s NAB Show (booth C2336) to debut its new audio processor hardware, APRO-CLC01 for use with Continuous Loudness Control (CLC).

Designed for integrators, this new solution for custom hardware enables engineers to use the company’s processing algorithm for continuous loudness and dynamic control of a live signal in their professional audio equipment.

“We have created the APRO-CLC01 as a platform that will enable integrators or processor manufacturers to use RTW’s OEM-PCB within their hardware, as well as console manufacturers and others,” explained Michael Kahsnitz, head of product management, RTW. “With this new introduction, it will be up to the integrator to define the way a user can control and read back information from our processor.”

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

RTW says the major advantage of the algorithm is its real-time capability, as well as its ability to, during processing, ‘learn’ about the dynamic structure and intention of the sound signal and in turn adopt its processing to predict what will come next.

“Another added benefit,” added Kahsnitz, “is users could have the ability to see otherwise hidden applications, giving them the option of modifying a dozen parameters via displays with numeric and graphic readings. In various other hardware devices, some of the applications do not give users a visual at all. This means the adjustment would be standard to the equipment and there is no way for the broadcaster or network operator to change anything. With RTW’s new APRO-CLC01, integrators now have the option to customise their experience, allowing broadcasters to see the OEM in action if they choose.”

Like all of RTW’s audio metering and additional equipment, APRO-CLC01 is compatible with EBU-R128 and all other major global loudness standard specifications.
