iZotope Announces RX Loudness Control

iZotope tell us their new automatic loudness correction tool aptly named, RX Loudness Control, delivers loudness-compliant mixes at the highest quality. It's a plug-in designed for broadcast Pros.

Cambridge, MA (March 25, 2015) - iZotope, Inc., a leading audio technology company, today announced its new RX Loudness Control plug-in. RX Loudness Control will help audio post production and broadcast professionals automatically and reliably create high-quality, industry-compliant mixes. RX Loudness Control will be unveiled and available for pre-order at NAB 2015 in booth SL4330.

With the widespread adoption of loudness standards worldwide, the responsibility often remains with content creators to ensure that programs are delivered within the appropriate tolerance of the required loudness standard. With RX Loudness Control, video and audio editors can easily choose the broadcast standard they wish to adhere to from a set of global templates. In faster than real time, RX Loudness Control automatically analyzes the audio and renders out a compliant file and an accompanying .CSV-formatted loudness report in just two clicks.

While there are several loudness monitoring and measurement tools on the market, the task of actually bringing the levels into compliance has remained until now a largely manual, time-consuming process. With quick turnaround becoming more and more an accepted norm, the possibility of having a show rejected due to loudness issues has been an ongoing concern. RX Loudness Control takes the guesswork out of conforming to loudness standards regardless of region and editor expertise.

"We're thrilled to offer post and broadcast professionals an automatic loudness correction solution that meets their needs for quality and accuracy," said Matt Hines, Product Manager at iZotope. "RX Loudness Control will give users absolute confidence in their work, while being easy to use and compatible with most major audio- and video-editing platforms."

The intelligent DSP processing inside RX Loudness Control is brand new and was developed specifically to guarantee transparent loudness correction, and to offer loudness tolerance metering across a range of program types. RX Loudness Control supports mono, stereo, and surround channel counts, up to 5.1, for seamless integration into any workflow.


RX Loudness Control supports the Audiosuite DPM and AAX plug-in standard for Avid Media Composer and Pro Tools. RX Loudness Control is also integrated into Adobe Premiere Pro's open extension API, bringing offline loudness-compliant processing to the Adobe platform for the first time ever.

Pricing & Availability

RX Loudness Control is available for pre-order at NAB 2015 for $299 (£205 / €279) (MSRP $349 / €325 / £239), with an expected release in Spring 2015.

    Hey Rounik, do you know if RX Loudness Control is a break out of the Loudness plugin in RX 4 Advanced? Or is this a totally separate and different functionality? From the sound of it it seems to be redundant functionality if you already own RX 4 Advanced. On the other hand, if you don't, this is a great tool for making the loudness of your mix compliant to a standard without the need to buy the whole RX restoration suite. Chris

    Hi Chris, That's a good question. I've not had the chance to try it out yet... I'm thinking that RX Loudness Control, being designed for video broadcast purpose, is derived from RX Advanced. So if you have RX 4 Advanced and/or Ozone, for example, then you'll probably not need RX LC. Having said that, it's just supposition on my part and I couldn't say yet with any kind of authority one way or the other. :)
