APU Spectrum Analyzer is a free spectrum analysis tool supporting a variety of FFT configuration options. You can adjust the FFT window type (Rect, Hann, Hamming, Blackman, Kaiser) and size (from 64 up to 65536) to suit your needs. Monitor spectrum in real-time with variable history size, or load an external file for full spectrum analysis.

Quickly switch between standard dB ranges or auto-range and view the frequency spectrum in log, linear, or note-based scale. Supports histogram hold for measuring long term frequency response. You can also adjust the bucket size independent of the FFT size and take snapshots of the frequency response for reference.

Spectrum Analyzer is a state-of-the-art spectrum analyzer plugin, which offers a lot of opportunities to display the spectral content of your audio material and helps you create a better mix this way. SpectrumAnalyzer comes in two editions, a free and a full version. SpectrumAnalyzer offers a mode based on bandpass filters, and not only FFT like many others. This allows a much better oversight of the frequency balance of a mix.

Fast & Precise Detection
SpectrumAnalyzer uses modern and reliable technics to analyze your audio material. It 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 cool 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.

View Multiple-Tracks Simultaneously
Check out the cool and unique auxiliary feature. This functionality 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.

An analyzer designed for low-end detail.

The Reflex Spectrum Analyzer includes the standard features you’d expect from this category of plugin—such as stereo comparison and the ability to tilt and smooth the display. Where this plugin stands out is its ability to show responsive and granular bass information. Technically speaking, the device uses four 512-element FFT analyses in a multiband configuration with distinct sample rates, chosen to optimize the distribution of the resulting 1,024 frequency bins across the audible range. The design achieves low-end bin spacing of just 0.7Hz, equivalent to that of a single 65,536-element FFT.

The combined frequency amplitude spectrum is displayed in a streamlined fashion on a semitone log scale covering 11 octaves from 10Hz to 20kHz. While the laws of information theory prevent us from viewing low-frequency information at high resolution in both the time and frequency domains simultaneously, Reflex brings you closer to what’s possible.

Features

132 log-spaced frequency bands with semitone spacing from 10Hz to 20kHz
90dB range
Adjustable smoothing across frequency and time
Left-Right and Mide-Side stereo modes
Short-term (i.e. 3-second) LUFS display
Adjustable spectrum tilt (0, 3dB or 4.5dB per octave)
Peak frequencies displayed on a chromatic scale (calculated without tilt)
Adjustable GUI size (S, M & L buttons)
Click/drag over the spectrum display to audition specific frequencies (vertical position controls filter width)
Connect a second signal via sidechain input to compare spectra (if using the AU format of the plugin, also click “Sidechain Compare”)
Technical notes

Available in VST3 format for PC, and VST3 & AU formats for Mac. AAX support coming soon
Requires a compatible Digital Audio Workstation or other plugin host
Supports common sample rates from 44.1 to 384kHz

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.
