MasterCheck from NuGen Audio is a loudness metering plug-in that allows you to instantly hear how your mixes are affected by loudness-matching algorithms used by streaming apps, download stores, websites, and podcasts. The software analyzes your tracks to let you know how they respond to codecs and bandwidths across a variety of music delivery services, and gives you the tools to ensure that your music reaches your listeners sounding the way originally intended, on Spotify, Apple Music, Youtube, and more.
