JadeSpectrogram by Jade Hochschule 0 (0)

is a VST3/AU plug-in for real-time spectrum analysis. It gives you access to many of the analysis parameter, like the used window or the FFT-size. The display of the analysed data can be changed afterwards. It is possible to change the displayed frequency range and the colourmap (and its dynamics).

Voxengo SPAN 3.11 (Win/Mac) Free 0 (0)

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

This audio plugin can be loaded into any audio host application that conforms to the AudioUnit or VST plugin specification. Plugins with AAX version available can be loaded in ProTools 12+.

This plugin is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10 and later versions) and macOS (10.7 and later versions, 64-bit Intel processor-based) computers (2.5 GHz dual-core or faster processor with at least 4 GB of system RAM, SSE4.2 instructions support required, e.g. any Intel Core i-, AMD Bulldozer- or Zen-based processor). A separate binary distribution file is available for each target computer platform and audio plugin specification. If supported on a specific processor, the plugin may internally utilize AVX2-optimized code.

Compatible Windows and macOS plugin software: Cubase, Logic Pro, ProTools, Ableton Live, Reaper, Presonus Studio One, FL Studio, Cakewalk, Nuendo, WaveLab, GarageBand, Vegas, SoundForge, Audition, Samplitude, Digital Performer, Mixcraft, Bitwig Studio, Edius, others.

If you cannot get plugin to work on macOS High Sierra/Mojave, you have to logout from the system and login again, it’s a known issue not caused by plugin’s own bug.

List of changes in version 3.11:
Added Apple Silicon native compatibility.
Added 1/48 octave spectrum smoothing option.
Improved spectrum smoothing precision.
Enabled the “asynchronous drawing” window mode on macOS; may fix the user interface “lagging”.
The “Copy to” button is now called the “Copy”: this button now copies parameters FROM the selected group, NOT TO the selected group. This should improve the workflow.
Improved font rendering slightly.

LVC Audio LVC Meter 1.0.9 Mac Win AU VST VST3 AAX FREE 0 (0)

LVC-Meter 1.0.8
-updated September 29, 2020-
Meter: LVC style

LVC-Meter is a free plugin that builds on all of the metering features of Toned-MAX, Limited-Z, and Clipped-MAX. This may be nothing new, but there might be times when you need the LVC style meters but not all of the other plugin features.

Beyond Basic

LVC-Meter includes a spectrum analyzer, stereo vectorscope, and a waveform history view. All of the meters utilize true-peak monitoring for determining intersample peak levels (i.e., “overs”). In addition, LVC-Meter functions in EBU mode, K-System metering, and standard dBFS mode.

Just Because

Why have a meter plugin that monitors stereo and true-peak levels without having the ability to adjust things? Good question, and LVC-Audio agrees. LVC-Meter includes three simple but valuable controls: GAIN, BALANCE, and WIDTH. Both the GAIN and BALANCE controls have extra fine settings accessible by right-clicking on the knobs. These extra settings allow for precise gain and balance adjustment. Perfect for a final gain stage.


Adjustable true-peak level for visualizing overs
Resizable interface
User configurable colors
Configurable spectrum analyzer settings (e.g., window type, fft size, overlap)
FloatDither: 32-bit dithering based on Chris’s work at Airwindows (
XML-based preset system for saving, importing, and exporting user presets
System Requirements and Specifications

Windows: VST, VST3, and AAX plugin formats. LVC-Meter requires Windows Vista, Windows 7, or Windows 8 machines with a processor that supports SSE2 (AMD or Intel processor from around 2004 or later). An iLok device is required to use the AAX format.
OS X: AU, VST, VST3, and AAX plugin formats. LVC-Meter requires OS X 10.8 or later, and an Intel Core2Duo processor (or better). An iLok device is required to use the AAX format.

Hornet Plugins HoRNet Freqs free spectrum analyzer plugin 0 (0)

HoRNet Freqs is a spectrum analyzer that provides two different kind of visualization of the audio spectrum, the first one is called “analog” and is inspired to an analog hardware spectrum analyzer that is still found on the master of many recording studios even today. The second one is called “digital” and it’s our own take on the typical spectrum analyzer based on the FFT (the standard math to transform an audio file into its spectrum components).


– Two different spectrum views, analog and digital.
– Selectable dBs range.
– Three different integration times.
– Peaks display and reset.
– Preset save and load.
– GUI is scalable and hardware accelerated.
– macOS (>=10.9) and Windows (Windows 7 an later) support.
– 64-bit plugin for Mac and Windows.
– Audio Units VST2.4, VST3 and AAX format.
