Spectral Modeling Synthesis

Spectral Modeling Synthesis (SMS) generally refers to any parametric creation of a short-time Fourier transform, i.e., something besides simply inverting an STFT, or a nonparametrically modified STFT (such as standard FFT convolution). A primary example of SMS is sinusoidal modeling, and its various extensions, as described further below.
