- About Us
Mix and Master for the listener - directly to Apple, Spotify, DAB Radio and TV specifications, MasterCheck Pro will immediately reveal how your audio is going to sound to the listener, allowing you to produce with confidence and certainty.
MasterCheck Pro is the complete solution for optimising your mixes for today’s music delivery services. Streaming apps, download stores, websites and podcasts all use data compression, loudness matching or both. These processes can affect your mixes in various undesirable ways: your loud punchy mix could end up quiet and flat, or suffer clipping or distortion. The good news is you don’t just have to mix for CD and hope for the best. MasterCheck Pro reveals problems ahead of time, and enables you to deliver masters perfectly tuned for specific playout systems.
"I have to deliver final mixes that will sound great on multiple streaming services, radio, iTunes & in clubs. MasterCheck Pro allows me to do this... It might be the most important tool in my arsenal."

Cross Platform Mastering
How do people listen to the music you mix? You work hard to deliver masters that sound great at home, in the car or on earbuds, but that’s only half the story. How does your mix sound on Spotify, Apple Music or Google Play? What about YouTube, digital radio, or Beatport? MasterCheck Pro will show you; giving you a unique advantage and enabling you to take back control of the listening experience. You’ll instantly hear how your tracks are affected by loudness matching algorithms on different devices and services, and you’ll know how your masters respond to different codecs and bandwidths.
One Plug-in, Complete Toolset
MasterCheck Pro gives you the tools to make sure your mix reaches the listener sounding as you intended. Industry standard meters show the Loudness and PLR (dynamic range) of your mix and how they compare to your target platform. Loudness auditioning reveals any level changes and compression that will be applied. External reference auditioning and metering lets you A/B your master FX chain with other music or your uncompressed mix. True Peak Metering ensures you’re within the delivery spec and guarantees you’ll stay clip-free at later encoding stages. Real-time codec auditioning previews your mix through different encoding schemes and quality settings.
Playout services have a ‘letter box’ through which they deliver your audio. If you’re lucky it slides through; if not, the service will force it to fit .A heavily maximized master might win the loudness war on CD, but could simply be turned down on your music service or player. This leaves valuable headroom you could have used for transient detail and punch. With MasterCheck Pro’s Loudness and PLR features you can find the sweet spot between perceived loudness and dynamics, perfectly tuning your master to the format.
The major online music services and stores encode your music in various formats, often using different bit-rates depending on your device or account type. Encoding “hot” mixes can often introduce true peak overs that will clip on playback. MasterCheck Pro will detect these errors, allowing you to stay within a safe limit. You’ll also be able to hear any obvious frequency masking or other artifacts, and try to mitigate these effects at the mixing and mastering stages.

"For me, the biggest draw for MasterCheck and NUGEN Audio's Visualizer Suite are their high degree of customizability for both the GUI and the specs. I have two instances of Visualizer and one of Master Check on all my sessions, which gives me several different metering, analyzer, and RTA options along with different meter ballistics and different scales."
MusicTech Magazine | Hollin Jones
"It's always been crucially important to meter your audio properly during the mastering process, but as technology changes the rules of the game shift... It's [MasterCheck] incredibly important for mastering engineers or anyone producing music for broadcast."
