Blue Cat’s FreqAnalyst

Blue Cat’s FreqAnalyst by Blue Cat Audio is a real-time spectrum analyzer that helps you understand the frequency balance of your audio. Rather than shaping the sound, it provides a visual reference for checking bass buildup, midrange congestion or high-frequency energy while mixing. Mono and stereo analysis make it useful on individual tracks or a full mix. Smooth interpolation keeps the graph fluid even at high frequency resolution, while adjustable conversion settings let you tailor the analysis to your workflow. Zoom into a specific frequency range for closer inspection, and use absolute or relative thresholds to highlight relevant spectral detail. A customizable interface, preset management, undo/redo and MIDI control add flexibility. Processing winds down when the input is silent to conserve CPU. It suits home producers who want a clearer view of what they hear without adding another sound-shaping effect.
