Abstract
A method for humanizing a music sequence (S), the music sequence (S) comprising a multitude of sounds (s1, . . . , sn) occurring on times (t1, . . . , tn) comprises the steps generating, for each time (ti) a random offset (oi), adding the random offset (oi) to the time (ti) in order to obtain a modified time (ti+oi); and outputting a humanized music sequence (S′) wherein each sound (si) occurs on the modified time (ti+oi). According to the invention, the power spectral density of the random offsets has the form 1 f α . wherein 0<α<2.
