Documentation

Produce a set of delta coefficents for a track

The delta function is used to produce a set of coefficients which estimate the rate of change of a set of parameters. The output track <parameter>d<parameter> must be setup before hand, i.e. it must have the same number of frames and channels as <parameter>tr</parameter>.

Parameters:

tr - : input track of base coefficients
d - : output track of delta coefficients.
regression_length - : number of previous frames on which delta estimation is calculated on.
