BC FreqAnalyst 2 VST(Stereo)

Blue Cat's FreqAnalyst is a free spectrum analyzer plug-in that lets you monitor the spectral content of your audio signal in real time. This plug-in has been designed to provide extreme smoothness and high resolution for both time and frequency: unlike most spectrum analyzers, Blue Cat's FreqAnalyst is able to display continuous variations even with a very high frequency resolution, thanks to its unique smooth interpolation algorithms.
