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.
Most aspects of the audio to frequency display conversion can be managed, which gives you total control over the monitoring. A special thresholding system has been developed to help you see the important parts of the spectrum easily. In case you need extra precision in a particular frequency range, you can zoom the display and check the part of the graph you are interested in.
This plug-in supports Blue Cat's skinning language so that you can customize the user interface to your personal needs. For more advanced capabilities, check Blue Cat's FreqAnalyst Pro plug-in, an extended version that offers many more features, such as saving/restoring curves, precise measurement tools, 3D spectrogram view, MIDI output. For multiple tracks analysis, you can use Blue Cat's FreqAnalyst Multi plug-in.
