- Abstract
The article explains the generation of natural-synthetic spectra in computer music by means of adaptive frequency modulation (AdFM). Two elements were used as the basis of this synthesis technique. These are the use of phase modulation of an input signal and the use of an arbitrary, monophonic, pitched or quasi-pitched input. The use of variable delay line or heterodyning are the two basic methods for achieving the phase modulation effect. The qualities of AdFM synthetic signal is experimented using flute and clarinet inputs. The possibilities of synthesizing different types of harmonic and inharmonic spectra were explored using the piano and voice inputs.
