MFCC is a spectral domain feature. Hence, it is important that a MFCC feature vector carries information solely derived from the sound signal under analysis. Sound is a non-stationary signal. A spectral domain analysis technique, such as Fourier analysis, is designed to give meaningful interpretation for only stationary signals.

MFCC is a technique designed to extract features from an audio signal. It uses the MEL scale to divide the audio signal’s frequency bands and then extracts coefficients from each individual frequency band, thus, creating a separation between frequencies. MFCC uses the Discrete Cosine Transform (DCT) to perform this operation.

DCT extracts the signal's main information and peaks. It is also widely used in JPEG and MPEG compressions. The peaks are the gist of the audio information. Typically, the first 13 coefficients extracted from the Mel cepstrum are called the MFCCs. These hold very useful information about audio and are often used to train machine learning models.

One popular audio feature extraction method is the Mel-frequency cepstral coefficients (MFCC), which has 39 features. The feature count is small enough to force the model to learn the information of the audio. 12 parameters are related to the amplitude of frequencies. The extraction flow of MFCC features is depicted below:
