NUGEN Audio presents new products at IBC 2012

Jul 23, 2012

The NUGEN Audio ISL inter-sample True-Peak limiter is designed for the
control of peak levels in audio signals from mono through to 5.1.

At IBC2012, NUGEN Audio will be displaying a range of industry-leading innovations for loudness correction that offer a smarter approach to meeting new loudness regulations and raising the quality of broadcast audio.

NEW — ISL: Inter-Sample True-Peak Limiter

The NUGEN Audio ISL inter-sample True-Peak limiter is designed for the control of peak levels in audio signals from mono through to 5.1. Unlike traditional approaches to limiting, ISL offers a true brick-wall solution, measuring inter-sample peaks and allowing the user to define the true-peak limit of the audio output (rather than the more traditional threshold control at which limiting begins to take effect).

Easy to use and totally transparent, ISL is based on the standardized true-peak algorithms of ITU-R B.S. 1770 and related standards, and is suitable for the control of audio for post production and broadcast applications. True Peak limiting can also be used to ensure that down-stream codecs (mp3, AAC etc.) do not introduce distortion into the signal. While ISL has been designed for limiting relatively dynamic high-quality audio, it can also be used to hard limit and reduce dynamic range considerably if this is required.

VisLM: Visual Loudness Metering that Shows Exactly What's Happening in a Mix

With detailed, objective loudness measurement, history and logging facilities, VisLM provides an easy to use ITU, ATSC and EBU standard-compliant way to measure, compare and contrast loudness during production, broadcast and post production, on the fly or for entire sections of audio. Offering true-peak level metering (inter-sample accurate level monitoring), loudness range (to help decide if and how much dynamic compression to apply), momentary 'instantaneous loudness' for mixing by ear, short term loudness (3 second time window) and program loudness (long term integrated loudness measurement), VisLM is a comprehensive tool that helps audio professionals cut through the complexity of loudness compliance.

VisLM is available in two versions, VisLM-C (compact) and VisLM-H (history) and both versions are available in 2.0 and 5.1 formats.

LM-Correct: Integrated, Short-Term, and True-Peak Loudness Correction for Avid Editors

NUGEN Audio LM-Correct is an audio suite plug-in designed to offer automatic, faster than real-time loudness analysis and correction within Avid edit systems, including Media Composer, Pro-tools, and News Cutter.

LM-Correct is ideal for rapid, intuitive correction in situations where time is limited, providing an automatic method of rapidly conforming audio to current loudness standards. LM-Correct can be used as a one-stop solution for loudness correction, fixing audio that has not been mixed with loudness standards in mind, or in conjunction with a real-time loudness meter such as VisLM to 'fine tune' audio mixed to loudness requirements from the outset. LM-Correct can also be used as a final 'back-stop' processor, ensuring that finished files are within specification and performing an in-place fix where errors are found.

LM-Correct can be used within a project to measure and correct audio without needing to leave the editing environment, enabling rapid in-place loudness normalization of mono, stereo or multi-channel audio. It is also possible to use LM-Correct within Avid batch processing for fully automated file handling.

LMB: Batch Processing Loudness Correction Tool for High Throughput Applications

The NUGEN Audio LMB system is an off-line file-based loudness analysis and correction program designed for rapid assessment and correction of files for loudness and true peak content to ITU-R BS. 1770/1, ITU-R BS. 1770-02, and EBU R128 based specifications.

With a drag and drop interface and/or specific watched folders, LMB saves operator time by automatically handling the process of checking and conforming files to multiple broadcast criteria. LMB produces detailed post-mortem logs and includes an in-built graphing facility and can be fully integrated into an automated system using the optional command-line interface and XML file output logs.
