Spectrum Analyzer is a real-time audio analysis plugin designed to capture the essence of classic hardware analyzers. It offers a unique approach by using filter-bank algorithms instead of the common FFT method, delivering a distinctive visual representation of audio frequency content. This design choice provides a different set of advantages for monitoring and understanding sound characteristics during music production or mixing.

The plugin features multiple octave modes, including 1/3, 1/4, and 1/6 octave options, corresponding to 30, 40, and 60 frequency bands. It simultaneously displays peak, peak-hold, and average (RMS) levels, allowing detailed insight into the dynamic behavior of audio signals. Users can switch between bar, curve, and curve fill visualization modes to suit their preferences or workflow.

Spectrum Analyzer offers a fully customizable interface with adjustable ballistics and color settings, alongside an unrestrictedly resizable display window that adapts to any screen size. It supports all sample rates, making it suitable for a wide range of audio projects and environments. This plugin combines classic analyzer aesthetics with modern flexibility to enhance audio monitoring tasks.
