Homomorphic filtering is used in the log-spectral domain to separate filter effects from excitation effects, for example in the computation of the cepstrum as a sound representation; enhancements in the log spectral domain can improve sound intelligibility, for example in hearing aids.

Famous quotes containing the words speech and/or analysis:
“Does any one suppose that private prayer is necessarily candid—necessarily goes to the roots of action! Private prayer is inaudible speech, and speech is representative: who can represent himself just as he is, even in his own reflections?”
—George Eliot [Mary Ann (or Marian)
“Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.”
—Octavio Paz (b. 1914)
