Voxengo AnSpec User Guide
Introduction
AnSpec is an analog-style one/third-octave spectrum analyzer plug-in 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 plug-in, you can still
change level meter ballistics and resize plug-in’s window.
Features
1/3 octave analog-style spectrum analyzer
Peak level indication

Compatibility
This audio plug-in can be loaded into any audio host application that conforms to the
AAX, AudioUnit, VST or VST3 plug-in specification.
This plug-in is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10
and later versions) and macOS (10.7 and later versions, 64-bit Intel processor-based)
computers (2.5 GHz dual-core or faster processor with at least 4 GB of system RAM,

User Interface Elements
Note: Most interface elements (buttons, labels) located on the top of the user
interface and on the bottom are standard among all Voxengo plug-ins and do not
require much learning effort. For an in-depth description of these and other
standard user interface elements and features please refer to the “Voxengo Primary
User Guide”. Learned once it will allow you to feel comfortable with all pro audio
plug-ins from Voxengo.
Parameters
Since AnSpec does not feature any other adjustable parameters beside user interface
window size, there is nothing to write about. Spectrum ballistics can be adjusted via
the “Settings” window.
Note that like in all analog spectrum analyzers, the spectrum in AnSpec has a natural
upwards (left to right) +3 dB per octave slope.
