A model for multi-pitch and periodicity analysis of complex audio signals is presented that is more efficient and practical than the Meddis and O'Mard (see J. Acoust. Soc. Am., vol.102, p.1811-20, 1997) unitary pitch perception model, yet exhibits very similar behavior. We also demonstrate how to apply this model to source separation of complex audio signals such as polyphonic and multi-instrumental music and mixtures of simultaneous speakers. Such analysis techniques are important for automatic transcription of music and structural representation of audio signals
