描述----------Description----------
DEPRECATED: Computation of MFCCs — this has been replaced by melfcc already and is just a wrapper! Will be removed shortly.
建议使用:计算MFCCs - 这已经取代melfcc已经只是一个包装!很快就会被移除。
用法----------Usage----------
MFCC(object, a = 0.1, HW.width = 0.025, HW.overlapping = 0.25,
T.number = 24, T.overlapping = NA, K = 12)
参数----------Arguments----------
参数:object
Object of class Wave.
对象类Wave。
参数:a
Coefficient for a first oder diffenrence filter, which is used to pre-emphasize the signal in first step of feature extraction.
第一化成diffenrence的过滤器,这是用来预强调特征提取的信号在第一步骤的系数。
参数:HW.width
Width of Hamming window in seconds, which is used to divide the signal into frames.
Hamming窗口的宽度,在几秒钟内,它是用来划分为帧的信号。
参数:HW.overlapping
Fraction of how much the Hamming windows should overlap.
分数的多少海明窗重叠。
参数:T.number
Number of triangular channels on the mel scaled spectrum, which are mapped to the signal.
梅尔缩放的频谱,其分别对应的信号的三角通道数目。
参数:T.overlapping
IGNORED!
忽视!
参数:K
Number of desired output quefrencies the inverse discrete cosine transformation.
所需的输出逆频数的逆离散余弦变换。
注意----------Note----------
This function was always documented to be in development and highly EXPERIMENTAL!!!
此功能总是记录是在发展的,高度实验性的!!
