Blue Cat's FreqAnalyst Pro is a powerful real-time spectrum analyzer designed for detailed audio spectrum analysis. It provides smooth and accurate frequency response with customizable parameters such as slope and offset correction. The user interface is fully customizable, featuring adjustable transparency to allow seamless integration into any workflow. A spectrogram view displays the evolution of the spectrum over time, adding depth to the analysis process.

This plugin supports both mono and stereo signals, offering instant, peak, and average frequency curve displays for each channel. Memory slots enable users to save and recall frequency response curves, simplifying A/B comparisons during mixing and mastering. The display includes zoom capabilities and precise measurement tools, ensuring in-depth monitoring of audio content.

One of the standout features of Blue Cat's FreqAnalyst Pro is its ability to convert audio frequency data into MIDI CC or automation curves in real time. This function allows producers and sound designers to control other effects or MIDI hardware dynamically based on the pitch content of the audio signal. The plugin is available as a standalone product or as part of larger bundles, with a demo version provided for evaluation.
