SpectrumAnalyzer

SpectrumAnalyzer free spectrum-analyzer by SIR Audio Tools

SpectrumAnalyzer is a free spectrum analyzer VST, VST3, Audio Unit, AAX plugin developed by SIR Audio Tools. Compatible OS(s): Windows 64b, macOS.

SpectrumAnalyzer is a spectrum analyzer plugin that offers a lot of opportunities to display the spectral content of your audio material, which helps you create a better mix. SpectrumAnalyzer comes in two editions, a free and a full version.

SpectrumAnalyzer has a FFT (Fast-Fourier-Transform) and an analog-style (parallel band-pass IIR filter) engine, both of which can run simultaneously. So you can benefit from the more accurate time resolution of the band-pass filters and the better frequency resolution of the FFT at the same time. Check out the intelligent peak-detection, which automatically detects resonant frequency peaks in the signal. Use the snapshot function to easily save the current state of your analyzer, so you can compare the spectral profile of your current project with other songs. SpectrumAnalyzer also includes a VU-Meter (with peak and RMS measurement) and a Stereo Correlation Meter.

SpectrumAnalyzer features an auxiliary feature that makes it possible to send audio from one SpectrumAnalyzer instance into other instances. This is a quite powerful tool, because you can set up as much aux-sends as you want, and then you can easily switch between them as input source. For example, you have different subgroups and want to see the spectrum of all of them in one SpectrumAnalyzer instance: put a single SpectrumAnalyzer instance on every track and activate the aux-send. Now you can comfortably switch between these aux-channels in your master SpectrumAnalyzer instance. In the full version, you can open up to 4 slots in one plugin instance.

SpectrumAnalyzer has nearly endless adjustment possibilities. To name a few: FFT-Size & Window. Number of Bands/Filter-Steepness and Bandwidth (analog style bandpass analyzer). Time Resolution & Release speed. Optional Peak Hold and intelligent Peak Detection. Spectral RMS with adjustable integration. Mid and Side Signal detection. Adjustable Colors, two different spectral smoothing algorithms. Display Range and Slope/dB. Adjustable GUI size and scaling. Optional gradient and shadow effects.

Spectrum Analyzer

Spectrum Analyzer free spectrum-analyzer by Seven Phases

Spectrum Analyzer is a free spectrum analyzer VST plugin developed by Seven Phases. Compatible OS(s): Windows.

Spectrum Analyzer is a real-time spectrum analysis VST plugin. The idea was to create an old-fashioned tool reminiscent of classic hardware analyzers of the earlier centuries. Unlike most of other analyzers available these days, this plugin is not FFT-based but utilizes a filter-bank algorithms that mould its unique pros and cons.

Features:

  • 1/3, 1/4 or 1/6 octave mode (30, 40 or 60 bands respectively).
  • Simultaneous peak, peak-hold and average (RMS) display.
  • Bar, Curve and Curve Fill modes.
  • Entirely adjustable ballistics.
  • Unrestrictedly resizable display window.
  • Customizable colors.
  • Supports any sample rate.

Sonic Visualiser

Sonic Visualiser free spectrum-analyzer by Centre for Digital Music at Queen Mary

Sonic Visualiser is a free spectrum analyzer plugin developed by Centre for Digital Music at Queen Mary, University of London. Compatible OS(s): Windows 64b, macOS, Linux.

Sonic Visualiser is an application for viewing and analysing the contents of music audio files. The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

As well as a number of features designed to make exploring audio data as revealing as possible, Sonic Visualiser also has powerful annotation capabilities to help describe what you find, and the ability to run automated annotation and analysis plugins.

Features include sophisticated spectrogram views; multi-resolution waveform and data displays; manual annotation of time points and curves; measurement capabilities from spectrogram and spectrum; playback at any speed; looping and playback of discontiguous selections; ability to apply standard audio effects and compare the results with their inputs; and support for onset detection, beat tracking, structural segmentation, key estimation and many other automated feature extraction algorithms via Vamp audio analysis plugins.

Sonic Visualiser contains features for the following:

  • Load audio files in WAV, Ogg and MP3 formats, and view their waveforms.
  • Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters.
  • Annotate audio data by adding labelled time points and defining segments, point values and curves.
  • Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views.
  • View the same data at multiple time resolutions simultaneously (for close-up and overview).
  • Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on.
  • Import annotation layers from various text file formats.
  • Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio.
  • Play back the audio plus synthesised annotations, taking care to synchronise playback with display.
  • Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops.
  • Time-stretch playback, slowing right down or speeding up to a tiny fraction or huge multiple of the original speed while retaining a synchronised display.
  • Export audio regions and annotation layers to external files.

The design goals for Sonic Visualiser are:

  • To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data.
  • To facilitate ready comparisons between different kinds of data, for example by making it easy to overlay one set of data on another, or display the same data in more than one way at the same time.
  • To be straightforward. The user interface should be simpler to learn and to explain than the internal data structures. In this respect, Sonic Visualiser aims to resemble a consumer audio application.
  • To be responsive, slick, and enjoyable. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory.
  • To handle large data sets. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. (Disk space is another matter. Sonic Visualiser eats that.).

MultiInspectorFree

MultiInspectorFree free spectrum-analyzer by VertexDSP

MultiInspectorFree is a free spectrum analyzer VST, Audio Unit plugin developed by VertexDSP. Compatible OS(s): Windows, macOS.

MultiInspectorFree is a 31 band spectral analyzer designed to be used in a multitrack environment and provides an easy way for simultaneous spectral analysis of several audio signals.

The first instance of MultiInspectorFree behaves like a standard 31 band spectral analyzer. Additional instances automatically send their spectral analysis result to all other instances of MultiInspectorFree. Every editor window of MultiInspectorFree shows the same content. Therefore, after opening all necessary plug-in instances it is sufficient to leave just one editor window open. The width and the color of the level bars are adjusted according to the current number of instances.

MultiInspectorFree incorporates a standard third octave frequency analyzer. The centre frequencies of the bands are based on the ISO 266:1997 standard (20 Hz to 20 kHz). Pink noise will appear flat in the frequency spectrum.

MultiInspectorFree supports up to 4 instances at a sample rate of 44.1 kHz.
