Spectral Synthesis and String Synthesis

Spectral Synthesis 
Also known as SMS, spectral modeling synthesis which is an acoustic modeling approach for speech and other signals. It considers sounds as a series of harmonic content and noise content. The harmonic components are identified based on peaks in the frequency spectrum of the signal. The signal that remains following the removal of the spectral components (white noise) is passed through a time filter. The output is the frequencies of the detected harmonic components and the time-varying filter.

String Synthesis
Ken Freeman, audio designer, couldn't afford a mellotron to play his string parts so he invented a new string synthesis to imitate the string sounds. I found this physical model of string synthesis to be very interesting because it digitally presents visuals of the strings being plucked with the sounds of each string. https://www.youtube.com/watch?v=bUyupapSwZY
