This MEGA plugin combines the functionality of at least three other plugins in a very clever way. AND it's free!
Growl Audio has released gFractor, a completely free spectrum analyzer plugin for macOS, Windows, and Linux.
Until now, I've been using tools like Voxengo SPAN, Youlean Loudness Meter, or Goodhertz Canopener Studio for these features.
In this video, I walk you through every feature of this impressive tool, from mid/side and transient/tonal analysis to the built-in stereo metering, LUFS loudness meter, and reference track comparison via sidechain.
