What Blue Cat’s FreqAnalyst Pro does
The analyzer offers a spectrum view, a spectrogram view and a 3D waterfall view, and the 3D display can be fully controlled. Analysis parameters are adjustable, slope offset correction is available, and a smart interpolation algorithm keeps the displayed curves very smooth. Instant, peak and average curves can be shown for each channel on the same graph, and the response is shaped by two threshold systems whose time behavior is set by attack and release parameters.
Four memory slots store any curve, so setups from several tracks or effects can be compared side by side with easy A/B comparison, and curves can be saved. Zooming on all displays is animated, and a note information display plus exact coordinates support precise measurement. Output parameters can be recorded as automation curves or sent as MIDI CC messages, covering minimum and maximum frequencies and energy centre.
Key features
- Mono and stereo mid/side analysis. The real-time spectrum analyzer works on mono signals and on stereo signals split into mid and side, with analysis parameters that can be set in full.
- Memory slots and curve comparison. Four memory slots store any curve, and saved curves can be compared against one another with easy A/B comparison to set up tracks and effects side by side.
- Automation and MIDI output. Output parameters are recorded as automation curves and can send MIDI CC messages, with transformation parameters for offset, amount and reverse, and the generated envelopes cover minimum and maximum frequencies and energy centre.
- Precision and offset controls. Slope offset correction and precision rate settings are applied to the measured spectrum, and custom absolute and relative threshold controls set how the display responds.
- Idle shutdown and smooth bypass. When fed silence, processing shuts down smoothly, and the smooth bypass switches the plugin on and off without audible noise.
