The Visualizer from NUGEN Audio is a spectrum-analyzer plug-in that is designed for use in a multitude of recording, mixing and mastering situations. It is compatible with Mac and Windows and requires use of a host program that supports Avid, Audio Units, or VST plug-ins.
The Visualizer is an audio-analysis tool that can help you identify problematic frequencies, fundamentals, harmonics and much more. It has several visual displays including a traditional spectrum-analysis display, a spectrogram display that shows level and frequency history with a zoom control, and primary and secondary meter displays which allow for multiple metering types to be viewed simultaneously. Some of the different metering types include standard peak and RMS metering, K-Scale meters and a stereo margin indicator that displays dB remaining until clip.
The software is designed to be helpful in a wide variety of use cases. It features a -20 dBFS RMS pink noise signal generator that can be used for acoustical testing purposes. It can be used to aide in "room tuning" for analyzing the acoustical properties of acoustic spaces such as control rooms, live rooms, auditoriums and more. Use Visualizer in recording situations for helping to determine mic placements, for EQing and more. Use it in mixing and mastering for investigating hard-to-hear low-frequency issues, honing in on problem areas, examining phase relationships, peak monitoring and more.
