Produce multiple sets of delta coefficents from a waveform.

Documentation

Produce multiple sets of delta coefficents from a waveform.

Calculate specified types of delta coefficients. This function is used when the base types of coefficients haven't been calculated. This function calls sig2coef to calculate the base types from which the deltas are calculated, and hence the requirements governing the setup of <parameter>fv</parameter> for sig2coef also hold here.

Parameters:

sig - : input waveform
fv - : output coefficients. These have been pre-allocated and the number of channels in a indicates the order of the analysis.
op - : Features structure containing options for analysis order, frame shift etc.
slist - : list of types of delta coefficients required.
