Factorsynth

Factorsynth is an experimental tool for sound modification and cross-synthesis based on matrix factorization. The input sounds are decomposed into a set of spectra and a set of temporal functions, which can be then recombined in several ways to obtain the output sound. It can be understood as a spectral editing tool in which the elements to be manipulated are of a relatively high abstraction level, compared to analysis/resynthesis systems based on manipulating individual time-frequency bins, such as those based on the spectrogram or phase vocoder. In Factorsynth, the elements to be manipulated can be, for instance, entire musical notes, attack portions, inharmonic structures, impulsive events.
