![]() This action means transitioning from the time-domain to the frequency-domain. To create a cepstrum, a Fourier transformation of an oscillogram (i.e., a complex acoustic waveform) is first executed to create a spectrum. What are cepstrum, cepstrogram and quefrency-domain?

If this is the case, you first open Finder, select the Go menu, and then press the alt key ⌥. (However, sometimes the Library folder is hidden on a Mac OSX.

Therefore, cepstral analysis of voice sounds has become a conditio sine qua non in clinical voice assessment. (2014)– the cepstrum with its related analysis techniques and markers has proven to be a feasible, valid and robust domain for measuring voice quality/dysphonia severity. (1994) and Hillenbrand
