 Mel-frequency cepstrum

Mel-frequency cepstrum (MFC) is a representation of the short-term power spectrum of a sound signal that is commonly used in the fields of speech and audio processing. It is particularly important in applications such as speech recognition, speaker identification, and other areas involving acoustic signal analysis. ### Key Concepts: 1. **Mel Scale**: - The Mel scale is a perceptual scale of pitches that approximates the way humans perceive sound frequencies.
