cepstrum for dummies

What is MFCC in simple terms?
In AI, MFCC (Mel Frequency Cepstral Coefficients) is a feature extraction method for speech and audio analysis.
It transforms raw audio signals into a compact representation that captures important frequency and temporal information.
What does cepstrum tell us?
The cepstrum is a representation used in homomorphic signal processing, to convert signals combined by convolution (such as a source and filter) into sums of their cepstra, for linear separation.
In particular, the power cepstrum is often used as a feature vector for representing the human voice and musical signals.
Cepstral Analysis, a tool used to detect periodicity in frequency spectrum, can be useful in gearbox fault detection in vibration analysis.
It identifies equally-spaced sidebands in the spectrum produced by tooth meshing errors, providing insight into modulation frequencies and diagnosing the error.
