Saw the review for this in an audio mag.
https://www.soundonsound.com/reviews/nugen-audio-mastercheck-pro Seems to be 2 versions, MasterCheck $129; MasterCheck Pro $199.
From SOS review:The Pro extension to MasterCheck takes this plug-in to a whole new level, with the key difference being its new facilities to allow the
user to hear (as well as see) how a track will work on different media platforms. Importantly, this doesn’t just mean how it will be affected by the various loudness-normalisation standards, but also by the actions of specific lossy codecs and different bit-rates used in the various transmission/streaming services.
