Object-Based Sound Source Modeling for Musical Signals

Authors: Tolonen, Tero

AES Convention 109 · Paper 5174 · September 2000

Abstract

This study presents a framework for audio and music processing, which comprises an analysis and a synthesis path that are connected at three-representational levels. Auditory signal analysis techniques include a multipitch analysis model, an event detector, and sinusoidal modeling which are combined in an iterative sound separation system. Techniques are presented for detection of perceptually relevant features, such as inharmonicity, vibrato and decay characteristic, from polyphonic mixtures of harmonic sounds. The integration of the analysis and synthesis parts is illustrated with examples, where two-voice acoustic guitar signals are analyzed into an object-based representation and resynthesized using sound source models.:
