# 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

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).
