trscale trscale trscale Streaming partial track frequency scaling. The trscale opcode takes an input containg a TRACKS pv streaming signal (as generated, for instance by partials) and scales all frequencies by a k-rate amount. It can also, optionally, scale the gain of the signal by a k-rate amount (default 1). The result is pitch shifting of the input tracks. fsig trscale fin, kpitch[, kgain] fsig -- output pv stream in TRACKS format fin -- input pv stream in TRACKS format kpitch -- frequency scaling kgain -- amplitude scaling (default 1) ain inch 1 ; input signal fs1,fsi2 pvsifd ain,2048,512,1 ; ifd analysis fst partials fs1,fsi2,.003,1,3,500 ; partial tracking fscl trscale fst, 1.5 ; frequency scale (up a 5th) aout tradsyn fscl, 1, 1, 500, 1 ; resynthesis out aout The example above shows partial tracking of an ifd-analysis signal and linear additive resynthesis with pitch shifting.
