MasterCheck provides metering for loudness monitoring (LUFS/LKFS), dynamic range (PLR/PSR), real-time comparison to reference tracks (via the NUGEN Send plug-in), codec preview functions and true-peak level compliance metering (ITU, afclip). The MasterCheck plug-in provides a more traditional loudness metering and level optimization, geared towards music mastering as well as streaming services that use proprietary data compression and loudness matching algorithms. It should be noted that the ISL meter is designed as a True Peak meter (not a traditional loudness meter), which measures the highest point of an analog signal, versus a Sample Peak meter, which evaluates only the digital signals, as it has become important to closely monitor peak levels for the best possible conversion to lossy codecs, like MP3. NUGEN has provided presets that comply with ITU-R BS.1770, and Apple's afclip standards that offer the ability to create level compliant masters for iTunes, Netflix, or any other streaming or broadcast standard. ISL thoughtfully provides the ability to listen to the difference signal, or gain reduction effects only, of the limiting process to help fine-tune the processing against any undesirable artifacts. Additional controls affect lookahead, release time, comprehensive dither, and noise shaping options. Steering and Ducking work along with and are affected by the Linking function of the limiter. NUGEN provides further metering options, called Steering and Ducking, which display the byproducts or interaction between left and right channels as one or both channels trigger the limiting action. The output meters display the resultant stereo output levels as dBFS (True-Peak). The second meter displays the amount of gain reduction as one of two user-selectable display styles. The first section displays the post input gain stereo input levels. The limiter activity is displayed via three metering sections. The ISL provides an input gain control, and a separate true-peak limit, or ceiling control. Essentially a mastering limiter, or maximizer, ISL provides an inter-sample True Peak limiter with comprehensive and flexible metering along with dithering. The most utilitarian plug-in of the Modern Mastering Bundle is called ISL True Peak limiter. I have used NUGEN plug-ins for a few years now, and have found that by learning about and applying these plug-ins, I have developed a better sense of the applications of audio levels and feel I can easily meet the expectations of content producers, distributors, and, ultimately, the intended audience.

These are professional tools, and you will benefit from spending a good amount of time learning to use each plug-in. The three plug-ins, each one available as AAX, RTAS, VST2, VST3, and AU versions, provide level control and several different types of audio analysis, from visual analysis of levels and imaging, to visual and audible level comparisons of your master to various streaming standards. The NUGEN Audio Modern Mastering Bundle combines three sophisticated plug-ins that each play a vital role in creating masters in the modern world of audio production for music, podcasts, audiobooks, and multimedia. The mastering engineer takes on the roles of quality control, metadata oversight, and of course, producing impressive sounding, competitive audio.
Mastering audio today involves more than just creating loud and exciting stereo music masters.
