Anyone know? FOF (formante onde function) is an additive method that uses a periodic impulse and a bank of tuned resonant filters as exponential sinewave generators, while PAF (phase aligned formant) is a modulation method that shapes a sinusoidal function with a lobed window at a subfrequency synchronised to the main oscillator. In FOF the partials are given explicitly by the filter coefficients, but in PAF the sidebands are a result of modulation. FOF has more in common with the vocoder while PAF is a special case of general VOSIM (wave packet method). > > Jamie > > -- > www.postlude.co.uk > > > _______________________________________________ > PD-list@iem.at mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list -- Use the source _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
