WebMel-frequency cepstrum. In sound processing, the mel-frequency cepstrum ( MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients ( MFCCs) are coefficients that collectively make up an MFC.
