Nugen Audio updates LM-Correct, Loudness Management Batch

Nugen Audio has released an update to its LM-Correct loudness analysis and correction tool and its Loudness Management Batch (LMB) processor. The update adds a dialogue gate option to both tools that enables sound engineers to measure dialogue sections within source material automatically.

Dialogue gating can be used to automate dialog-anchored loudness measurement and correction, facilitating decisions based on the loudness of sections with dialogue in the source material. In conjunction with other loudness parameters, the dialogue measure can also be used as an indicator of dialog clarity.

“The addition of a dialogue-gated measurement adds an additional level of flexibility to our offline loudness tools,” says Jon Schorah, creative director of NUGEN Audio. “We are committed to providing tools that meet ITU, ATSC (CALM Act), and EBU standards. Adding a dialog gate option ensures our users have the ongoing ability to comply automatically with the full range of broadcast delivery specifications based on current international loudness standards.”

In addition to the dialog gate option, new presets within LM-Correct add a 10-second, short-term loudness sliding window that works in conjunction with the dialogue-gated program loudness. Similarly, LMB benefits from the addition of a fully adjustable short-term sliding window parameter, making it possible to adhere to specifications based upon variants of the typical EBU three-second measure.

The updates are free for all current users.
