Examples of org.vocvark.jAudioTools.FFT

org.vocvark.jAudioTools.FFT
This class performs a complex to complex Fast Fourier Transform. Forward and inverse transforms may both be performed. The transforms may be performed with or without the application of a Hamming window.

The FFT is performed by this class' constructor. The real and imaginary results are both stored, and the magnitude spectrum, power spectrum and phase angles may also be accessed (along with appropriate frequency bin labels for the magnitude and power spectra). @author Cory McKay
