Blue Cat’s Audio Analysis Pack gives you pretty much everything you need to analyze and measure the frequency content of audio in one convenient package. The pack contains a dazzling array of useful plug-ins, all of which are available individually as well. Among these are two frequency analysis plug-ins, both of which provide performance equal to that of dedicated spectrum analyzers. Furthermore, these plug-ins let you can control other plug-ins–and even MIDI instruments–with the resulting measurements.
Specs and useful features
Because this is a review of spectrum analyzer plug-ins, we will focus on those specific types of plug-ins in the pack.
First up is FreqAnalyst Multi, which provides a variety of spectrum analysis features for multiple tracks. Ideally-suited for mixing and mastering, it provides a detailed view of the frequency and time of several tracks simultaneously, all from a single screen. A useful and versatile mixing tool, it will also find plenty of use as a frequency overlap detector.
The second smartphone plug-in is FreqAnalyst Pro, which adds automation generation capabilities and a 3D viewer to the standard set of spectrum analysis features.

5. Photosounder Spiral
Demo & Price
To describe Photosounder’s Spiral as a music analysis plug-in would be accurate–but it does underplay its capabilities a bit. Spiral certainly does a great job of revealing the frequency content of music, but its fresh and innovative approach to audio analysis places it so far ahead of other plug-ins that it is almost in an entirely different category.
Frequencies are displayed in a spiral (no surprise there), with a chromatic band encircling it. It is a simple enough concept to be sure, but the ability to see what is going on in your music quickly and intuitively is noteworthy. Spiral also provides many other features that give you a more detailed and informative view of your audio.
Specs and useful features
In the Spiral display, individual instruments have specific colors that represent their unique positions in the stereo mix. The plug-in also makes it possible to capture or record bits of audio into memory and play it back at slower speeds. This feature is helpful for identifying individual notes or deciphering chords.
You can even adjust the resolution at which stored audio plays back. You can lower the resolution for more precise time measurement for instance, or increase it when you need to analyze low-frequency instruments or complex chords.
User impressions
Users found Spiral to be as useful as an audio analysis tool as a musical aid. The bright colors and stereo separation make it possible to identify tones and notes quickly and accurately.
As a learning tool, Spiral is pretty much incomparable in the world of spectrum analyzer plug-ins. Its ability to highlight specific sections of the audio, capture it, and play it back at slower speeds are features that simply don’t exist in any other spectrum analyzer plug-in.
Bottom-line
Spiral probably isn’t the best choice for analyzing audio for mixing or mastering purposes. More a musical aid than a frequency analysis tool, it should nevertheless find a welcome place in your plug-in collection.
6. 2nd Sense Audio Mixing Analyzer
Demo & Price
2nd Sense’s Audio Mixing Analyzer hides an impressive wealth of features in a simple and modernistic interface. Like the best spectrum analyzer plug-ins, it allows the real-time monitoring of multiple tracks of audio, with the data viewable from a single window. It also identifies instances where frequencies collide and mask each other. Whether you need to pinpoint problem frequencies in specific audio tracks or simply want to check your level balances, Audio Mixing Analyzer could be a useful tool.
Specs and useful features
Like other spectrum analyzer plug-ins that allow for the monitoring of multiple audio streams, Audio Mixing Analyzer is meant to be loaded onto each track to be analyzed. All tracks will then be visible on any instance of the plug-in, each in a different color. You can also label each track as you see fit.
A vertical line will pop up on the display if any frequencies clash or overlap. You can then instantly see where two or more parts are occupying the same frequency range. An included threshold knob lets you control how frequencies clashes are displayed, with shorter instances showing up as more pronounced movements of the indicator line.
A scrolling display below the spectrum display provides real-time information on the clashing frequencies, as well as the measure and beat position where they occur. There are also illuminating blocks to the left that indicate the presence of tracks with conflicting frequency content.
Free Lufs Vst
User impressions
Audio Mixing Analyzer may be fairly simple, but users seem satisfied at the amount of information provided. By presenting data as text as well as visual form, users can identify frequency clashes easily, and quickly determine what steps to take to remedy potential issues.
Bottom-line
Audio Mixing Analyzer isn’t the most fully-featured spectrum analyzer around. In fact, it is one of the simplest in this rundown, without a lot of esoteric display settings and customizability options onboard. Nevertheless, it is a capable enough analyzer for the most part, and it should find plenty of use in any studio.
7. Voxengo SPAN
Demo & Price
Voxengo’s SPAN is something of a classic in the audio world, providing spectrum analysis capabilities equal to that of the best plug-ins. Remarkably, SPAN is free, which makes its professional features and capabilities even more impressive.
Even so, Voxengo saw fit to release an “extended” version of SPAN, dubbing it the SPAN Plus. Building on the already impressive features of its freeware predecessor, SPAN Plus added a static spectrum display option, PNG file export, and the ability to import and export spectrum data in real-time.
Specs and useful features
SPAN Plus has a new “mode” system that gives you the flexibility to set the display according to your preferences. This feature lets you view Fourier block size in samples, and lets you set the overlap percentage of the FFT window. You can also specify the visual slope of the spectrum, change how the secondary spectrum is displayed, and even smoothen out the spectral display as desired.
SPAN Plus makes it possible to perform a variety of analysis methods. You can compare the spectrums of different tracks at the same time, with unique colors for each channel.
User impressions
SPAN Plus especially impresses users with its ability to perform multi-track comparisons from a single window. The ability to compare EQ curves pre- and post-mastering on the same graph makes it a flexible and useful tool for mixing and mastering.
It is interesting to note that many users find the free SPAN to be just as capable as the SPAN Plus for their needs. But that is more a testament to the excellence of the free plug-in than it is a criticism of SPAN Plus.
Bottom-line
SPAN Plus is an excellent spectrum analyzer plug-in in more ways than one. Admittedly, you could get pretty much the same features in the free version of SPAN. But if the ability to compare the spectrums of two different audio sources at the same time is important to you, SPAN Plus is a no-brainer.
Spectrum Analyzer VSTs
What is spectrum analysis?
In an audio and musical context, spectral analysis is the process of measuring the frequency content of audio signals. Using a function known as “Fourier transform”, audio is broken down into its component frequencies and displayed on a screen.
Spectrum analyzers–purpose and function
Spectrum analyzers essentially provide visual representations of sound. They measure the frequencies of audio signals and display the results in a graph in real-time. The horizontal axis represents the pitch/frequency of the audio, while the vertical axis represents the amplitude. Pitch/frequency is measured in Hertz, and amplitude is measured in decibels.
By providing a visual representation of audio, spectrum analyzers make it easier to identify specific areas of the frequency range that may cause problems in the mix later on. When used in conjunction with standard audio monitoring, spectrum analyzers can enhance efficiency during the mixing and mastering processes.
Essential features
The display is the most important part of a spectrum analyzer. This is where you can see the frequency content of your audio and how “hard” specific frequencies are hitting. You can then figure out which frequencies you will have to cut or boost to fix any problem.
The best spectrum analyzers give you more specific details on frequencies and levels when you place your cursor at certain points on the display. Some plug-ins even allow you to zoom in for a more accurate view of the levels.
How to choose the best spectrum analyzer
Accuracy is, of course, one of the most important aspects of a spectrum analyzer. You will want to pay particular attention to this quality when comparing the different spectrum analyzer plug-ins available.
You should also look into the option to set the FFT block size a few different ways. This feature allows you to view frequencies at different resolutions, which could help you identify problem areas in specific frequency ranges.
One important thing to keep in mind is that spectrum analyzers can not–and should not–take the place of proper monitoring via speakers or headphones. By all means, use spectrum analyzer plug-ins for an added perspective while mixing or mastering. But don’t forget that what ultimately matters is how the music sounds–not how it looks.

LUFS
This measurement is basically like RMS but with a twist. It takes into account how humans perceive loudness and it is currently the most accurate way of measuring loudness. The main difference compared to RMS is that LUFS uses filters to shape the sound before processing in a similar way to how we hear the sound.
LRA
This measurement will give you an idea of the difference in volume between the verse, chorus and other sections of your track. If there is a big difference in loudness between the various sections of your track then your loudness range will be a higher number and vice verse.
DR
Dynamic range metering will show you the levels of the compression in audio. The algorithm is based on a difference between true peak and short term loudness. The current implementation is improved version of the “PSR” algorithm which has problems measuring dynamics in audio that has fast changing quiet and loud sections.
TP
Knowing the true peak value is really important since it indicates the true maximum level of audio after conversion to analog or different digital form such as conversion from WAV to MP3. If your audio goes above 0dB TP you might get clipping in converted audio.
