A Flexible Analysis-Synthesis Method for Transients
Harvey Thornburg, Fabien Gouyon · University of Michigan Library Repository · 2000
We propose a new transient model which naturally extends the sinusoidal model to nonstationary phenomena. An integrated online-o#ine segmentation approach is developed, followed by an explicitly time-variant sinusoidal model. 1 Introduction The sinusoidal model is a convenient soundrepresentation in analysis-synthesis frameworks. The signal is modeled as a sum of sinusoids, with timevariant amplitudes and frequencies, plus a residual r(n), or unmodeled part: y(n) = 2p # k=1 A k,n cos( # m
