Adaptive Additive Synthesis of Sound

Résumé

In the following article we investigate a new algorithm for additive sound synthesis that extends the standard approach by means of explicitly modeling a sound as a superposition of non stationary partials with time varying amplitude and frequency. Due to the extended model an adaptive parameter estimation is required. By means of a mathematical investigation we show, that it is possible to track a partials amplitude, frequency and phase by only adapting a subset of the model parameters and that a stable partial tracking requires the use of overlapping analysis blocks. We demonstrate the algorithm by means of additive synthesis of a synthetic and a piano tone.
