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.

# Added a weighting/slope editor supporting up to 10 user defined slope programs # Added ruler-tape tool (hold "alt" key and drag over the analyser) # Ridge mode added. Plots then block other plots below. Handy for crest indication # Added plot re-ordering # Fixed plugin resize mouse behaviour # Improved legend layout # Data resolution increased for large displays
# Added system vs audible bandwidth range option # Inverse masking option added (shows masked content only) # All peak modes now draw bin maximum, all RMS modes still draw the bin average # Multi-display fullscreen logic improved. # Config panel layout updated # Double clicking display area resets peak-hold # Animation framerate issues fixed
