pub unsafe extern "C" fn aubio_unwrap2pi(phase: smpl_t) -> smpl_t
compute the principal argument
This function maps the input phase to its corresponding value wrapped in the range \f$ [-\pi, \pi] \f$.
\param phase unwrapped phase to map to the unit circle
\return equivalent phase wrapped to the unit circle
