Requirements Based on License Type
UPG (upgrade): requires a qualifying previous license of NUGEN Audio's "Visualizer" (earlier version), registered on the same user account. A valid serial number from the previous version may be required during activation. This upgrade will not work without proof of ownership of a prior version.
What Visualizer 2 Is For
Visualizer 2 is an audio analysis plug-in designed to measure, understand, and correct your signals. It helps adjust input levels, monitor phase, control the stereo image, and identify problematic frequencies for precise EQ. In music, it facilitates centering vocals and mastering the low end; in post and broadcast, it ensures mono compatibility, image stability, and dialogue intelligibility.
Main Features
Smart Window and Accelerated Workflow
The smart window system allows assembling multiple views, automatically aligned and resized for optimal readability. User presets provide instant recall of interface configurations and sizes tailored to each production stage.
Advanced A/B Comparison
The Comparison mode compares two sources within a single instance: overlay, side-by-side display, and differential view. Ideal for judging the impact of a mastering chain, preparing an EQ matching, or spotting resonances to remove.
Phase and Stereo Control
Track overall correlation, correlation history, frequency correlation, and stereo distribution via the vectorscope and stereo bias meter. These tools help avoid mono cancellations and stabilize the image for broadcast.
Detailed Spectrum and Dynamics Reading
The stereo spectrogram and FFT analysis reveal fundamentals, harmonics, and hidden artifacts. The frequency/dB zoom, scrolling, and peak hold provide detailed inspection from low-mids to very high frequencies, as well as clear tracking of peaks and headroom reserve.

Is it possible to compare two mixes within a single instance?
The Comparison mode allows analyzing two sources within the same instance. Available views include overlay, side-by-side, and difference view. This feature can be used to evaluate the effect of a mastering chain or to prepare an EQ matching.
What tools are provided for phase and stereo control?
The analysis includes overall correlation, its history, and frequency-based correlation. A vectorscope and a stereo bias meter allow monitoring the stereo distribution and the risk of mono cancellation.
Is the software available both standalone and as a plug-in?
Standalone and plug-in versions are offered. The stereo spectrogram, FFT analysis, frequency/dB zoom, and peak hold functions allow detailed inspection of the spectrum and peaks.
