Voxengo AnSpec

AnSpec is an analog-style one/third-octave spectrum analyzer AAX, AU and VST plugin for professional music production applications.  It was designed to be a handy visual feedback tool for those who like visual smoothness and easiness of use of analog analyzers.  AnSpec also provides peak level indication.

While there are no adjustable parameters available in this plugin, you can still change level meter ballistics and resize plugin’s window.
