Mel-frequency cepstral coefficients (MFCCs) are coefficients that collectively make up an MFC. They are derived a type of cepstral representation of the audio clip (a nonlinear spectrum-of-a-spectrum ). The difference between the cepstrum and the mel-frequency cepstrum is that in the MFC, the frequency bands are equally spaced on the mel scale, which approximates the human auditory system s response more closely than the linearly-spaced frequency bands used in the normal cepstrum.

此MATLAB程序用于自相关函数的估计（包括直接法和FFT法），信号的频率估计（包括MUSIC, ROOTMUSIC，ESPRIT和MVDR）和功率谱的估计（包括LevinsonDurbin迭代法，BT法和周期图法），并附带相应的仿真图以便于对比(MATLAB for correlation estimate :direct and FFT transform frequency estimate of signals:MUSIC, ROOTMUSIC，ESPRIT和MVDR power spectrum estimate : LevinsonDurbin and BT,corresponding figures are accompanied to compare)
