MFCC: DEPRECATED: Mel Frequency Cepstral Coefficients
Description
DEPRECATED: Computation of MFCCs --- this has been replaced by melfcc already and is just a wrapper! Will be removed shortly.Usage
MFCC(object, a = 0.1, HW.width = 0.025, HW.overlapping = 0.25,
T.number = 24, T.overlapping = NA, K = 12)Arguments
a
Coefficient for a first oder diffenrence filter, which is used to pre-emphasize the signal in first step of feature extraction.
HW.width
Width of Hamming window in seconds, which is used to divide the signal into frames.
HW.overlapping
Fraction of how much the Hamming windows should overlap.
T.number
Number of triangular channels on the mel scaled spectrum, which are mapped to the signal.
K
Number of desired output quefrencies the inverse discrete cosine transformation.
