Nugen Audio’s VisLM-H provides an easy-to-use ITU, ATSC (Calm Act), and EBU standards-compliant way to measure, compare, and contrast loudness during production, broadcast, and post production, on the fly or for entire sections of audio. With detailed, objective loudness measurement, history, and logging facilities, VisLM helps audio professionals cut through the complexity of loudness compliance. VisLM offers true-peak level metering for inter-sample accurate level measurement, loudness range to support the application of dynamic compression, momentary
‘instantaneous loudness’ to assist with mixing by
ear, short-term loudness, and programme loudness to support long-term integrated loudness measurement. These essential parameters make VisLM ideal for the full range of audio post-production projects. With the recent release of VisLM 1.6, the tool is now available for the first time in the Avid AAX format and also provides a version
for 64-bit OS X platforms. In addition, VisLM now includes a timecode feature for relating loudness parameters directly to timecode references. This gives audio engineers and editors a clear, frame- accurate position for any alerts, true-peak overs, maximum values, and other indicators.

The Qualis Audio Sentinel surround sound audio monitor measures, monitors, and logs loudness and virtually every other parameter necessary to ensure optimum audio reaches broadcast viewers. The electronic equivalent of a human listener, the Sentinel operates unattended, eliminating continuous aural checks by skilled listeners. This ability significantly reduces personnel requirements and attendant costs while improving the consistency of audio monitoring. Its measurement and logging verify and document CALM Act compliance, conforming fully to all ITU BS1770, ATSC, FCC, and EBU requirements. Any deviation outside of the allowed range automatically generates alarms to the user’s choice of SNMP, email, or GPO. The Sentinel also measures, displays, logs, and alarms all pertinent audio parameters, such as downmix loudness, downmix compatibility, true peak levels, hum, channel balance, and other parameters required for quantifying audio quality. Since measurement data is available over the instruments network interface, both real-time and logged results may be viewed on any standard browser from anywhere in the world. Software included with the unit automatically creates reports of loudness conformance with CALM Act requirements, which are tied to as-run logs generated by the user’s automation system. Reports are typically generated daily in a format selected by the user and automatically emailed to appropriate personnel.

RTW’s latest introduction, the LQL (Loudness Quality Logger), is an innovative tool developed for collecting loudness measurement and true peak data. By giving users the ability to obtain a log,
analyse, and report, their experience is enhanced even further. The LQL is a natural extension of RTW’s range of innovative software options and is compatible with the TM7, TMR7, and TM9
TouchMonitor line of products. LQL enables data to be derived directly via an IP-connection from a capable TouchMonitor audio meter, as well as from external storage media such as a USB stick. Also included in the software are dual limit weighting, status information, marker, and various other reporting features. The new PC software is free of charge to users; however the SW20014 Logging Data Server licence is required to enable a TM7, TMR7, or TM9 series meter to be compatible with data export and additional display functions. The LQL will be available from the first quarter of 2014.

requirements. It offers a comprehensive momentary, short term, long term, and true peak readouts, as well as a warning and logging system that keeps track of users’ levels and alerts them when they have been exceeded (or fallen short). WLM Plus now features gain and trim controls for correction of loudness levels and a true peak limiter, which saves users the need to use additional equipment or software. WLM Plus is available at no additional charge to all WLM owners who
have valid coverage under the Waves Update Plan.

TC Electronic’s Radar Loudness Meter is available on multiple platforms and aims to give the user a tool that will display their overall loudness landscape in a single view. The flagship standalone loudness meter is the TouchMonitor that features a touchscreen with highly flexible layout options. It complies with all major broadcast standards and is available with either a 7in (TM7) or a 9in (TM9) touchscreen. Due to its massive amount of hardware I/O options (digital/analogue, balanced/unbalanced, AES, 3G SDI, etc) and stereo as well as multichannel capabilities, it is suited for any broadcast and production application imaginable, including ingest, transmission, production, film, post, and live production. Apart from running the Radar Loudness Meter, a complete range of audio metering tools are available for TouchMonitor, including Surround Sound Analyzer, Stereo PPM Meter, Vector Scope, BLITS, and more.
