This paper introduces the analysis and synthesis of vibrato in music audio. The analyzer separates frequency modulators from their carriers using a demodulation process. It then describes the frequency variations of a vibrato using a period-synchronized parameter set, and the accompanying amplitude variations using a source-filter model, both of which can be regarded slow-varying. The synthesizer, on the other hand, reconstructs a vibrato from a given set of parameters. Using this system we are able to retrieve specific characteristics of vibratos, or modify them to implement various audio effects.
