Blue Cat's FreqAnalyst Pro

Blue Cat's FreqAnalyst Pro is an exceptional software designed for providing extreme smoothness and high resolution for both time and frequency. It uses the same smooth algorithms as its little brother, Blue Cat's FreqAnalyst free plugin. The frequency analysis can be fine-tuned with precision and rate to apply an offset or slope to the measured spectrum. It offers two thresholding systems, and the time response can be changed through the attack and release parameters.

Each channel has three modes: peak, instant or average response, and you can view them all on the same graph. You can also provide exact coordinates and zoom in on the spectrum's characteristics. The software provides four memory slots to store any curve in memory, which helps you make comparisons between several tracks or effects setups very quickly.

You can use the spectrogram view to monitor the evolution of the spectrum over time using exact coordinates display and zooming capabilities. Blue Cat's FreqAnalyst Pro provides output parameters that you can use to control other effects in real-time. The automation envelopes or MIDI CC messages generated include the minimum and maximum frequencies and the energy center of the spectrum expressed in Hertz or as a MIDI note value.

The transformation parameters like offset, amount, and reverse let you customize the generation of these parameters and monitor the modifications on the value graphs. You can check out the Peak Meter Pro Tutorials to know how to use this capability within your favorite host.
With this unique functionality, you can 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, and anything else you can think of.
