Webb21 apr. 2016 · MFCCs Mean Normalization As previously mentioned, to balance the spectrum and improve the Signal-to-Noise (SNR), we can simply subtract the mean of each coefficient from all frames. filter_banks -= (numpy.mean(filter_banks, axis=0) + 1e-8) The mean-normalized filter banks: Normalized Filter Banks and similarly for MFCCs: WebbMFCC 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.
