Expose is a stand-alone application by Mastering the Mix that analyzes your audio masters and points out issues they may have with a number of common metrics considered when making a professional audio master.
You can choose the target destination, like CD, Club, or streaming services like Youtube, Spotify or Soundcloud and Expose will direct you to where you need to pay attention to for the mastering standards for each location.
It does so in a simple to understand fashion. Simply color the blue waveform red where the issues are.
There are four sections in Expose that give you detailed information about the loudness, peaks, stereo/phase information, and dynamic range of your audio.
