NUGEN Audio Updates LMB To Version 1.4 – Loudness Compliance Batch Processing

NUGEN Audio has expanded its range of loudness correction tools with the release of Loudness Management Batch (LMB) version 1.4. A complementary tool to NUGEN Audio’s VisLM and LM-Correct plug-ins, the LMB processor delivers network-based automated loudness processing of large numbers of audio and video files, without requiring user intervention.

Based on NUGEN Audio’s loudness monitoring and correction engine, LMB operates faster than real time on batches of files, saving time and preventing human error. For streamlined processing of video, LMB can automatically de-mux video to analyze the audio content without changing the original file. LMB’s Watched Folders automate the processing of files, and optional command-line operation allows for full integration into existing asset management systems and procedures.

New features in LMB 1.4 include de-interleaved file handling for the simultaneous consideration of multiple mono files in stereo to 5.1 configurations with user-definable file suffix identification. To enable more sophisticated workflow automation, LMB 1.4 introduces a pass tolerance window for file analysis and correction, allowing existing audio within tolerance to pass without correction. LMB’s summary and detailed logs now have a user-definable log frequency that specifies the time interval between selected parameter log entries, and optional corrected file suffixes can now be added to output files to assist with file identification in unified I/O folder setups. LMB 1.4 also has the ability to ignore test/alignment tones during analysis and processing.

A highly versatile tool for mixing, mastering, post production, film, and broadcast, LMB is typically used as part of a content management workflow, as a stage of QC to check compliance of incoming content from third parties, or as a routine way of double-checking content when editors are using other loudness tools in the studio. LMB can also be configured to establish loudness parity of batches of files prior to mixing and editing.

LMB is fully compliant with the latest loudness standards including ITU-R BS 1770, EBU R128, ATSC A/85 and many other regional localizations, offering a complete professional solution for loudness and true peak compliance. LMB checks and corrects for integrated program loudness, short-term loudness, and even loudness range (LRA) targeting — highly effective when optimizing material with a wide loudness range (such as movie soundtracks, some sports, and live music) for consumer systems. LMB also takes care of true peak levels using a built-in back-stop limiter.

Nugen’s LMB is available for OS X and Windows at $999.
