DIETZ2011_UNWRAPITD - unwraps the given itd using the sign of the corresponding ild

Usage

itd = dietz2011_unwrapitd(itd,ild,f_inst,tr)

Input parameters

`itd`	itd to unwrap
`ild`	corresponding ild value
`f_inst`	instantaneous frequency
`tr`	only apply the unwrap mechanism for ild greater than the threshold tr, because for values near 0 it could be wrong (default: 2.5)

Output parameters

itd

unwrapped itd

Description

dietz2011_unwrapitd(itd,ild,f_inst,tr) unwraps the given itd using the sign of the corresponding ild value. Unwrapping means, that the ild value is used to decide to which direction the itd belongs, which can be unclear for large values, because of the \(\pi\) limit (see Dietz et al. 2011, Fig. 2).
