Blue Cat Audio FreqAnalyst Pro
Spectrum Analyzer Plugin
Blue Cat's FreqAnalyst Pro is a real-time spectrum analyzer with advanced functionalities. It uses the same smooth algorithms as its little brother, it has been designed to provide extreme smoothness and high resolution for both time and frequency.
The frequency analysis can be fine-tuned in details: manage its precision and rate, apply an offset or slope to the measured spectrum. Two thresholding systems are available, and the time response can be changed thanks to the attack and release parameters. Three modes are offered for each channel: instant, peak or average response can be displayed on the same graph. Zooming capabilities and coordinates display let you exactly measure the characteristics of the spectrum.
The four memory slots let you store any curve in memory: it helps you make comparisons between several tracks or effects setup very easily.
A spectrogram view has been added so that you can monitor the evolution of the spectrum over time either in 2D or 3D (3D waterfall mode). All channels are of course available in this view, with exact coordinates display and zooming capabilities.
Like many of our other professional analysis tools, this plug-in also provides output parameters that you can use to control other effects in real time: the generated automation envelopes or MIDI CC messages include the minimum and maximum frequencies and the energy center of the spectrum, expressed in Hertz or as MIDI note value. With the transformation parameters (offset, amount and reverse), you can customize the generation of these parameters and monitor the modifications on the value graphs.
Thanks to this unique functionality, you can now control any effect with the pitch of the audio signal: imagine a filter on an instrument controlled by the pitch of another instrument, compression depending on the pitch of the signal... Anything is possible.
Thanks to Blue Cat's skinning language support and the included window opacity management feature, you can adapt the plug-in user interface to your personal needs and enhance your workflow.
