1. Voxengo SPAN

by: Voxengo

 
Voxengo SPAN
 

SPAN is a real-time “fast Fourier transform” audio spectrum analyzer plug-in for professional music and audio production applications. For the most part it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality.

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. Besides 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 colour can be chosen to taste.

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

New In Version 3.7

Version 3.7 adds the “True Peak/Sample Peak” switch which can be used to switch between true peak and sample peak indication.

2. Voxengo AnSpec

by: Voxengo

 
Voxengo AnSpec
 

AnSpec is an analog-style third-octave spectrum analyzer plug-in for professional music production applications.  It was designed to be a handy visual feedback tool for those who like visual smoothness and easiness of use of analog analyzers.  AnSpec also provides peak level indication.

While there are no adjustable parameters available in this plug-in, you can still change level meter ballistics and resize plug-in’s window.

Features

  • 1/3 octave analog-style spectrum analyzer.
  • Stereo and mono analysis.
  • Peak level indication.
  • All sample rates support.
  • User interface window resizing.
  • Zero processing latency.

System Requirements

This audio plugin can be loaded into any audio host application that conforms to the AudioUnit or VST plugin specification.

RTAS compatibility is available by using the FXpansion VST-RTAS adapter.

This plug-in is compatible with Windows (32- and 64-bit Windows XP, Vista, 7 and later versions) and Mac OS X (10.11 and later versions, 32- and 64-bit, Intel processor-based) computers (2 GHz dual-core or faster processor with at least 1 GB of system RAM required). Apple M1 native and Big Sur are supported.  A separate binary distribution file is available for each target computer platform for each audio plug-in specification.


3. MAnalyzer

MAnalyzer
 

MAnalyzer

Spectral analyzer and sonogram measuring average, infinite average, temporary maximum and infinite maximum. Smoothing spreads energy between ranges of frequencies for perfect optical recognition. Prefiltering providing for example equal loudness contours, which therefore implements a simplified human hearing. Super-resolution improves resolution in low frequencies, but keeps the speed of higher frequencies. Standard FFT analyzers have poor resolution in low frequencies due to logarithmical scale of human auditory system.

  • Super-resolution fixes this problem and provides high resolution in both high and low frequencies. 
  • Deharmonization reduces harmonics leaving only fundamentals, which is great for identifying relevant frequencies. 
  • Magnitude normalization for better optical comparison. Freeze mode. 
  • Copy/paste to clipboard to compare in another analyzer window. FFT sizes from 1024 to 16384. 
  • Overlapping and adjustable windows for maximal precision. 
  • Global preset management – using a title button you can save your settings, which are shared on the computer, so you can easily access them in another songs.

System Requirements

Windows

  • Windows Vista / 7 / 8 / 10 (32-bit or 64-bit)
  • VST / VST3 / AAX compatible host (32-bit or 64-bit)
  • Intel/AMD processor with SSE2 support

Always use 32-bit plugins in 32-bit hosts, or 64-bit plugins in 64-bit hosts!

64-bit plugins can’t work in 32-bit hosts even if the operating system is 64-bit. Do NOT use 32-bit plugins in 64-bit hosts. They would have to be bridged and can become slow and unstable.

Mac OS X

  • Mac OS X 10.9 and newer (64-bit only)
  • VST / VST3 / AU / AAX compatible host (64-bit only)
  • Intel/AMD processor with SSE2 support or Apple Silicon processor

Note: Please check your product PDF documentation for more information and installation instructions.


4. Blue Cat’s FreqAnalyst

by: Blue Cat Audio

 
Blue Cat's FreqAnalyst
 

Blue Cat’s FreqAnalyst is a free spectrum analyzer plug-in that lets you monitor the spectral content of your audio signal in real time. This plug-in has been designed to provide extreme smoothness and high resolution for both time and frequency: unlike most spectrum analyzers, Blue Cat’s FreqAnalyst is able to display continuous variations even with a very high frequency resolution, thanks to its unique smooth interpolation algorithms.

Most aspects of the audio to frequency display conversion can be managed, which lets you total control over the monitoring. A special thresholding system has been developed to help you see the important parts of the spectrum easily. In case you need extra precision in a particular frequency range, you can zoom the display and check the part of the graph you are interested in.

This plug-in supports Blue Cat’s skinning language, so that you can customize the user interface to your personal needs. For more advanced capabilities, check Blue Cat’s FreqAnalyst Pro plug-in, an extended version that offers many more features, such as saving/restoring curves, precise measurement tools, 3D spectrogram view, MIDI output. For multiple tracks analysis, you can use Blue Cat’s FreqAnalyst Multi plug-in.

Features

  • Mono and stereo real time spectrum analyzer.
  • Total control over the audio to frequencies tranformation.
  • Smart interpolation algorithm for extreme display smoothness.
  • Zoomable display with multiple sizes.
  • Custom absolute and relative thresholds.
  • Full MIDI control and automation support with silent, zipper-free parameters update, advanced response control and MIDI Learn.
  • No CPU load on idle: when the plug-in is fed with silence, the processing smoothly shuts down, to optimize the CPU usage of your Digital Audio Workstation.
  • Skinnable and customizable user interface with transparency management.
  • Smooth Bypass: activate/deactivate the plug-in with absolutely no noise.
  • Undo/Redo.
  • Full-featured integrated presets manager.
  • Any sample rate supported.

What’s New?

  • Arrow keys can now be used to navigate presets.
  • Improved smooth plug-in bypass (faster and smoother transition).
  • New high-resolution graphics for knobs.
  • Reduced disk footprint.
  • Misc DSP performance enhancements.
  • Improved GUI loading performance.

System Requirements

Mac OS

  • Intel processor
  • Mac OS 10.7 or newer (Catalina and Big Sur are both supported)
  • VST / VST3 / Audio Unit / AAX compatible DAW (32-bit or 64-bit)
