On the Parameter Estimation of Sinusoidal Models for Speech and Audio Signals

Research paper compares three sinusoidal models for speech and audio signal processing: standard Sinusoidal Model (SM), Exponentially Damped Sinusoidal Model (EDSM), and extended adaptive Quasi-Harmonic Model (eaQHM). The study finds eaQHM performs better for medium-to-large window analysis while EDSM excels with smaller analysis windows, suggesting future research should combine both approaches.
