  Classical soft graviton theorem gives an expression for the spectrum of low
frequency gravitational radiation, emitted during a classical scattering
process, in terms of the trajectories and spin angular momenta of ingoing and
outgoing objects, including hard radiation. This has been proved to subleading
order in the expansion in powers of frequency by taking the classical limit of
the quantum soft graviton theorem. In this paper we give a direct proof of this
result by analyzing the classical equations of motion of a generic theory of
gravity coupled to interacting matter in space-time dimensions larger than
four.
