Sonible true:balance (Download)
true:balance is spectral analyzer plug-in that makes it easy to compare the spectral distribution of your mix in reference to different spectral targets.

true:balance provides all the information and guidance you need for a well-balanced mix. An adjustable spectrum analyzer displays both the real-time spectrum of the input signal and the average spectrum over time. To meet listening expectations, true:balance also allows to compare the spectral distribution of a mix in reference to either different genres or custom reference tracks. Additionally, the plug-in provides you with information on the width and correlation of your track that will help you to avoid issues with mono compatibility or a blurry low end.
