  Compact binaries in hyperbolic orbits are plausible gravitational wave (GW)
sources for the upcoming and planned GW observatories. We develop an efficient
prescription to compute post-Newtonian (PN) accurate ready-to-use GW
polarization states for spinning compact binaries, influenced by the dominant
order spin-orbit interactions, in hyperbolic orbits. This is achieved by
invoking the 1.5PN accurate quasi-Keplerian parameterization for the radial
sector of the orbital dynamics. We probe the influences of spins and
gravitational radiation reaction on $h_+$ and $h_{\times}$ during the
hyperbolic passage. It turns out that both polarization states exhibit the
memory effect for GWs from spinning compact binaries in hyperbolic orbits. In
contrast, only cross polarization state exhibits the memory effect for GWs from
non-spinning compact binaries. Additionally, we compute 1PN accurate amplitude
corrected GW polarization states for hyperbolic non-spinning compact binaries
in a fully parametric manner and perform initial comparisons with the existing
waveforms.
