Mel-Frequency Cepstral Coefficients (MFCCs)

Mel-Frequency Cepstral Coefficients (MFCCs) are a representation of the short-term power spectrum of sound, commonly used in audio processing and speech recognition. They are derived from the Fourier transform of a signal and are designed to mimic the human ear's response to different frequencies. The MFCCs capture the timbral aspects of audio signals by transforming the frequency scale into the Mel scale, which is more aligned with human auditory perception. These coefficients are widely used in various applications, including voice recognition systems, music genre classification, and speaker identification, due to their effectiveness in capturing the essential features of audio signals.
