Melcepstral
Melcepstral is a term used in the field of speech processing and audio analysis to describe a set of features derived from the Mel-frequency cepstral coefficients (MFCCs). These features are commonly used in various applications such as speech recognition, speaker identification, and music information retrieval. The Melcepstral features are obtained by applying a cepstral analysis to the Mel-frequency spectrum of an audio signal.
The Mel-frequency scale is a perceptual scale of pitches judged by listeners to be equal in distance
The cepstral analysis involves taking the logarithm of the Mel-frequency spectrum and then applying the inverse
The Melcepstral features are typically used in conjunction with other features such as the delta and delta-delta
