[PD] derivation

[marius schebella]

hi,

there is an object lrshift~, ... but does not work for continuous data,
because it cannot handle the transition from one signal-vector to the
next...
so I think you will have to work with a subpatch working in block~ 1
blocksize. use for example the nop~ object from zexy and then go to the
outlet again. from the original and the "delayed by one sample"-signal you
can easy calculate the derivation of that step with
f ' (t)= f (t) - f (t-1).

Hello!

Is it possible to calculate derivations of an audio signal?
How do I do this?

Thanks!
