Abstract : In this work, we present an evolution of the DDS Damped & Delayed Sinusoidal model introduced within the framework of the general signal modeling. This model is named the Partial Damped & Delayed Sinusoidal PDDS model and takes into account a single time delay parameter for a set sum of damped sinusoids. This modi- ¯cation is more consistent with the transient audio modeling problem. We show the validity of this approach by compari- son with the well-known EDS Exponentially Damped Sinu- soids approach. Finally, the performances of three model high-resolution parameter estimation algorithms are com- pared on synthetic fast time-varying signals and on two typ- ical audio transients.
