Modèles Sinusoïdaux Étendus pour le Codage Audio

Abstract : In this paper, we present a short overview of several extended sinusoidal models. Two particular, models are then considered for the purpose of audio coding, namely the Exponentially Damped Sinusoidal model and the Damped and Delayed Sinusoidal model and we show their efficiency for the task of modeling special audio signal behavior (transient, pseudo-stationary, ...). Additionally, we expose an estimation algorithm based on a High-Resolution approach which is exploited in a deflation scheme. Finally, we propose these models as a basic tool in the heart of a sinusoidal audio coding architecture.
