RTW: Meters to mind loudness limits

13 September 2014

The Masterclass PlugIns Loudness Tools are making their IBC debut.

RTW’s standard-format DAW plug-in is the first in a new monitoring product line, initially in VST 2.4 format for Windows and RTAS for Mac OS. Full VST, RTAS and native AAX64 support on both platforms will follow.

Each RTW Loudness Tools Masterclass PlugIn visually depicts audio with all relevant level and loudness values as specified by international standards. It conforms to the EBU R128 loudness standard, as well as SPL, ITU-R BS.1770-3/1771-1, ATSC A/85, ARIB, and custom (to set OP-59, AGCOM). The company said it provides essential loudness metering without strangling the normal audio processing capability of the workstation.

The instruments provide graphical/numerical, as well as bargraph views, and can be freely rearranged and scaled. Various function parameters, such as integration time, operational range and tolerance, along with a number of viewing options for metering data and scales, offer extra flexibility.

RTW said the plug-in was also a handy tool for quality control, offering the precision and ease of use required to ensure compliance with custom specifications. Operation of the plug-in is highly intuitive,claimed the company, stating that even users without a great deal of experience in monitoring loudness can use it effectively.

The RTW Loudness Tools support all standard sampling rates up to 96 kHz and offer plug-in operation in mono, stereo and surround formats (eight channels maximum). The plug-in includes RTW’s Peak Program Meter, TruePeak, and Spot Correlator instruments and also offers all common loudness formats plus MagicLRA and an SPL view.

PACE anti-piracy and iLok USB copy-protection dongle are used for handling license management and plug-in activation. On an authorised computer, users can use unlimited RTW Loudness Tools instances.
