Best Spectrum Analyzer VST Plugins 2023

By segmenting the frequency spectrum to represent the range of frequencies, spectrum analyzers are tools that give the user detailed information about the sounds during music production. The frequencies are represented by the horizontal (x) axis, while their amplitudes are represented by the vertical (y) axis. The frequency range that can be heard by the human ear is typically from 20Hz to 20kHz, which is the range that is displayed on a spectrum analyzer.

iZotope Insight 2

Award-winning post production studios, music studios, and broadcast facilities all use the complete metering and audio analysis plug-in known as Insight 2. It is ideal for monitoring the intelligibility of your dialogue, troubleshooting troublesome mixes, visualizing changes made during mixing and mastering, and making sure that you are in compliance with broadcast loudness requirements.

With Insight 2, you can use real-time visual monitoring and color-coded warnings to quickly identify possible mix issues. Choose the meters you want to see, pick your chosen targets, and adjust the window to meet your current workflow to personalize your view. Any audio track in your DAW can be routed to Insight 2 to quickly assess loudness meter, levels, comprehensibility, spectral analysis, phase, frequency content, and other factors.

Like the most of the plugins created by iZotope, Insight 2 is an exceptional spectrum analyzer plugin that gives you all the resources necessary to have a comprehensive understanding of the track frequency range. The spectrum analyzer iZotope Insight 2 is an improvement over the first version of the stereo imaging plugin. Five modules that make up Insight can be opened simultaneously in a single, resizable window. The frequency and amplitude distribution of the signal as a function of time is shown on the spectrogram.

You can switch between mono, stereo, and surround viewing modes while using Sound Field to see where the sound signal is located. A vectorscope is in mono/stereo mode. The three other analysis modes in Vectorscope are Lissajous Vectorscope, which displays a plot of the samples on an oscilloscope multi, Polar Sample, which displays each sample individually as dots, and Polar Level, which displays the average levels of the samples intelligibility meter. A surround sound view is in surround mode.

The frequency vs amplitude graph is shown in the Spectrum Analyzer. By dragging a box over an area of interest or using the mouse wheel, you may zoom in on it. For a better comprehension of the graph, different spectrum types, such as Full and 1/3 Octave or Critical bands, can be chosen. Many producers and engineers view iZotope Insight 2 as the industry-standard spectrum analyzer. Even though it is less expensive than the original Insight plugin, this spectrum analyzer plugin is still very pricey. This is the Best Spectrum Analyzer VST Plugin in 2023.
