Requirements According to License Type
This product is an UPG upgrade to the latest version of "NUGEN MasterCheck." It requires ownership and activation of a valid previous MasterCheck license (proof required: serial number or eligible publisher account). If you do not own a previous license, please choose the standard version.
What NUGEN MasterCheck Is For
MasterCheck is designed to deliver masters optimized to current standards of Spotify, Apple Music, YouTube, Tidal, SoundCloud, podcasts, and digital radio. It reveals how normalization and encoding affect your mix, helps you find the sweet spot between perceived loudness and dynamics, and prevents downstream clipping through True Peak control.
Main Features
Broadcast and Encoding Simulation
Listen to your track as it will be delivered by streaming services using dedicated presets. Monitor artifacts in real time (frequency masking, distortion, stereo loss) and detect inter-sample peaks that will clip during playback.
Loudness and Dynamics Measurement
Track integrated loudness in LUFS, true peak, and PLR/PSR indicators to avoid over-compression. Prepare mixes with the right headroom before mastering while maintaining impact and micro-dynamics.
A/B Reference and "Offset to Match"
Instantly compare your mix to external references at equal levels, or neutralize gain added by an effects chain to judge processing exclusively, without volume bias.
Flexible and Secure Workflow
Resizable interface, configurable measurement splits, and customizable safety zones guide your decisions from quick setup to final checks before delivery.

Questions frequently asked
Is it necessary to already own MasterCheck to purchase this upgrade?

Is Nugen Audio MasterCheck UPG compatible with Mac and which formats are supported?
Compatibility includes OS X 10.9 with 1 GB of memory. Supported plugin formats are VST3, AU, and AAX.
Can Spotify, YouTube, or Apple Music be simulated before delivery?
Dedicated presets allow listening to the impact of normalization and encoding for Spotify, Apple Music, YouTube, Tidal, SoundCloud, podcasts, and digital radio. Artifacts such as frequency masking, distortion, or stereo loss can be auditioned in real time. Inter-sample peaks likely to cause clipping during playback are also detectable.
What loudness indicators are available for mastering?
Monitoring includes integrated loudness in LUFS, PLR and PSR indicators, as well as True Peak control. These measurements help preserve dynamics while preparing the broadcast level.
How to compare a mix with a reference at the same level?
The 'Offset to match' function allows level matching with an external reference or neutralizing the gain introduced by an effects chain.
