Attributes


Attribute-set

Various attributes and filters like Energy, Frequency, Similarity, Instantaneous, Band pass filters, Absorption quality factor, etc.
Spectral Decomposition with Fourier transforms and Continuous Wavelet transforms
Mathematical and logical expressions to create your own attributes and filters
Movie-style parameter testing (time gate or step out) to quickly find the optimal settings for your attributes.
