Description
Class Summary | |
---|---|
BasicDataWriter<T> | BasicDataWriter grabs forwarded feature data and prints it to a file in a simple format. |
BasicTimeDataWriter<T> | BasicTimeDataWriter grabs forwarded feature data and prints it to a file in a simple format. |
FFT | FFT performs a Fast Fourier Transform and forwards the complex data to any listeners. |
Frequency | Frequency processes spectral data forwarded to it by a PowerSpectrum
to determine the best estimate for the frequency of the current signal. |
GnuplotDataWriter<T> | GnuplotDataWriter grabs forwarded feature data and prints it to a file in pm3d format for Gnuplot. |
MelSpectrum | MelSpectrum receives spectral data from a PowerSpectrum object and
converts it to the mel frequency spectrum. |
MFCC | MFCC generates mel-frequency spectral coefficients, an important feature type in music and speech processing. |
PeakDetector | Detects peaks in a continuous stream of one element inputs. |
Power | Power calculates the RMS power over a frame directly from an audio signal. |
PowerSpectrum | PowerSpectrum calculates the power spectrum from the output of FFT . |
ReBin | ReBin takes an array of float data and places the data into a smaller array, the size of which is specified by the number of features. |
SpectralCentroid | SpectralCentroid calculates the spectral centroid of a signal. |
SpectralDifference | SpectralDifference calculates the spectral difference between one frame and the next. |
SpectralPeaks | Peaks finds the strongest N peaks in a signal passed from a PowerSpectrum ,
where N is the specified number of features. |
