How cepstrum analysis can be used for pitch detection?
Cepstrum pitch detection method In the logarithm of the magnitude spectrum, slowly varying components represent the envelop corresponding to vocal tract components and fast varying components represent the envelop corresponding to the excitation source.
What is the cepstral method?
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.
While a frequency spectrum or FFT reveals the periodicity of a time domain measurement signal, the cepstrum reveals the periodicity of a spectrum.
What is cepstrum analysis used for?
Cepstrum Analysis is a tool for the detection of periodicity in a frequency spectrum, and seems so far to have been used mainly in speech analysis for voice pitch determination and related questions.
