ifd analysis partials

jhearon


Curious about ifd analysis?  Is that an opcode or utility or something?  
Can't seem to find it.

ain inch 1                  ; input signal
fs1,fsi2 ifd ain,2048,512,1 ; ifd analysis
fst  partials fs1,fsi2,.003,1,3,500  ; partial tracking
      aout  resyn fst, 1, 1.5, 500, 1 ; resynthesis (up a 5th)
out aout

The example above shows partial tracking of an ifd-analysis signal and
cubic-phase additive resynthesis with pitch shifting.

The opcode name is actually pvsifd. It was renamed before the 5.00 release
because a name that begins with 'i' may conflict with variable names.
