Which analysis plugin would be best and easiest for determining if the L/R distribution of a track is even? I have some ear trouble now and then and would need an objective measurement. I'm mainly concerned about the bass, but of course the whole spectrum is interesting. I saw that Nugen's Visualizer has a L/R spectrum analyzer which seemed nice. Virtual Studio Technology and its acronym VST refer to an interface standard for connecting audio synthesizer and effect plugins to audio editors and hard-disk recording systems. VST and similar technologies allow the replacement of traditional recording studio hardware with software counterparts. Overall, the Spectrum 2 by Schulz Audio is another exciting spectrum analyzer plugin. Its most interesting feature is that it allows users to analyze multiple tracks for a single effect which is added to the master channel and is applied to all channels. Spectrum Analyzer is a free, Windows only, real-time spectrum analysis VST plugin. The idea was to create an old-fashioned tool reminiscent of classic hardware analyzers of the earlier centuries. Another unique (and quite experimental) feature of the plugin is its detached spectrum display window, freely resizable independently. Best Spectrum Analyzer VST Plugins A good spectrum analyzer plug-in is essential for letting you know what is going on with your audio. Even if you have a good monitoring system in your studio, a spectrum analyzer will help you identify potential problem areas in your mix.

Applications

Fast Fourier transform spectrum analyzer
Stereo, mid-side, surround spectrum analyzer
Stereo correlation meter
EBU R128, K-system meter
RMS, true peak level and clipping detector

SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer AAX, AudioUnit and VST plugin for professional sound and music production applications.

SPAN provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope. Beside that, you can choose to display secondary spectrum of a desired type (e.g. real-time maximum, all-time maximum). Spectrum can be smoothed out visually for an easier examination.

SPAN supports multi-channel analysis, and can be set to display spectrums from two different channels or channel groups at the same time. Spectrum's color can be chosen to taste.

SPAN also features output level metering with adjustable ballistics and integration time, EBU R128, K-system metering (including calibration K-system metering). SPAN displays level metering statistics, headroom estimation and true peak clipping detection. Correlation metering is available as well.

What Is Spectrum Analyzer?

Spectrum analyzers are tools that provide a user with detailed information about the sounds by dividing the frequency spectrum to show the range of frequencies. The horizontal (x) axis corresponds to the frequency and the vertical (y) axis corresponds to the amplitude of the frequencies.

The frequencies displayed on a spectrum analyzer are normally from 20Hz to 20kHz which is the range that can be heard by a human ear.

What Is The Purpose Of The Spectrum analyzer?

Spectrum analyzers are very useful to check the overall frequency balance of the mix or when comparing certain parts of a mix. This makes it especially useful when mixing using lower-quality monitors or in a non-treated (acoustically) room which can lead to an accidentally unbalanced mix.

What is the difference between a Signal Analyzer And Spectrum analyzer?

Both signal and spectrum analyzers have the same function. The only difference is that signal analyzers have digital signal processing (DSP) in order for it to solve functions like fast Fourier Transform (FFT). Signal analyzers can also have very high bandwidths.

What Is The Difference Between an Oscilloscope and a Spectrum Analyzer?

Oscilloscopes are normally used to find the time delay between two signals. On the other hand, spectrum analyzers are used to display and edit the frequency properties of a signal.

The difference between an oscilloscope and a spectrum analyzer is that the graph displayed in an oscilloscope is a graph of the signal against time, whereas the displayed graph in a spectrum analyzer is of the signal against frequency.

The figure above shows an example of an output waveform of a spectrum analyzer showing a graph of amplitude (in dB) against frequency (Hz).

What Is Reference Level In Spectrum analyzer?

The reference level is the maximum level of amplitude that can be displayed. For example, if we have the highest peak in volume of our signal at 20 dB and we set the reference level at 15 dB, then half of the waveform of that peak will be cutoff.

The 10 Best Spectrum Analyzer VST Plugins

1. Voxengo SPAN Review

More Info & Download

Voxengo SPAN is one of the most popular and widely used spectrum analysis plugins that you can find. It is a FREE plugin that manages to compete shoulder to shoulder with industry giants.

SPAN has an extremely flexible system that allows users to set up the spectrum analyzer preferences. Users can specify the Fourier block size in samples, set the percentage for the FFT window overlap, and specify the spectrum’s visual slope. In addition to that, Voxengo SPAN supports multi-channel display in both real-time and all-time maximums.

Key Features:

Voxengo SPAN has a real-time FFT spectrum analyzer
This plugin has a phase correlation meter that enables users to detect phase cancellations
Colorful interface with interchangeable colors
Users can listen to a specific frequency through a bandpass filter
K-level metering to prevent extreme loudness
Notes can be viewed as semitones and cents which is not a common feature among many other paid spectrum analyzers
GUI is scalable and users can zoom in into the spectrum to view specific ranges in detail

Voxengo has also released an extended version of the SPAN and it’s called SPAN Plus. On top of the features mentioned, SPAN Plus has many additional features like spectrum export into a PNG image, static spectrums display, and real-time spectrum import/export for comparisons between two tracks.

Compatibility:

Voxengo SPAN and SPAN Plus require Windows XP or higher for PC and macOS 10.11 or higher for Mac. It comes in VST/AU/AAX formats and supports both 32 and 64 bit systems for Windows but only 64-bi
