TDR Prism is a modern frequency analyzer with a focus on human audio perception. Easy to use and configurable, this audio plugin gives precise insight into the spectral properties of a signal. Among its flexible audio sourcing, decoding and visual configuration possibilities, Prism features a wide range of spectral weighting/tilting methods, peak/RMS smoothing options, including human auditory filters and real-time indication of auditory masking.

Prism is able to visualize and compare spectra from various sources, be it audio files, regular and sidechain inputs, or even other Prism instances in the project.

A freely resizable user interface with fullscreen support offers comfortable insight into the audio spectrum. Screen magnification, automatic marker lines and tone generator options further help inspect audio signals with ease.

Notable Features
Human auditory model incl. auditory masking
Wide range of tilting and weighting options
Supports sidechain inputs, external files, and links to other plugin instances
Visually appealing, high precision plotting
Freely resizable hardware accelerated user interface, incl. fullscreen support

System requirements
Windows Vista or above, Mac OS X 10.9 or above. OpenGL support.

Bertom EQ Curve Analyzer is an analyzer & signal generator plugin to see the frequency and phase response of any plugin (or hardware).

This plugin started as a developer tool but has been simplified so that it doesn’t require a complicated setup to work. Just sandwich the effect(s) you want to analyse between two instances, the first one set as the signal generator and the second one as the analyzer. Then set the latency if needed, That’s it! It also features a “group” system that enables to compare two analysis in real-time.

It’s particularly useful as a learning tool to see what classic EQs emulations are doing for example.

Cheap RTA is a 1/3 octave Real Time Analyzer.

• Classic 30 band display.
• 4dB per LED resolution.
• Resizable to a wide range of dimensions.

Runs on mono or stereo tracks. Stereo signals are summed to mono for frequency analysis, but your audio signal is passed through unchanged.

We kept the CPU load lightweight for this one, so it won’t bog down your system.

There are no parameters to adjust, but the window does allow resizing over a wide range of dimensions and aspect ratios.

Dust Analyzer is a configurable spectrum analyzer.

• Log-frequency (20Hz to 20kHz) dB-scale spectrum (also does linear).
• Fixed 8192 samples FFT (Nuttall window).
• Vertical division 10dB/line (totals 100dB from top to bottom).
• Freeze option (stops data update, survives editor close).
• Peak-hold.
