In their own words
Dusk Audio Spectrum Analyzer
Dusk Audio Spectrum Analyzer is a free, real-time plugin for measuring frequency spectrum, loudness, true peak, stereo correlation, and K-System headroom. Its FFT display offers 2048, 4096, and 8192 sample resolutions, with adjustable smoothing and slope and an optional peak hold. Loudness readings cover EBU R128 Momentary, Short-term, Integrated, and Loudness Range measurements. True peak detection follows ITU-R BS.1770-4 with 4x oversampling; the stereo correlation meter runs from -1 to +1. Channel views include Stereo, Mono, Mid, and Side. The manual describes it as a pure analyzer that leaves the audio path unchanged, so output matches input regardless of settings. It requires a 64-bit DAW supporting VST3, LV2, or AU. Listed formats are Linux VST3 and LV2, Windows VST3, and macOS VST3 and AU. Minimum systems are Debian 12+, Ubuntu 22.04+, or Fedora 36+ on Linux, Windows 10+, and macOS 10.13+. The plugins are free and open source, with source code on GitHub. The listed price is free.
