  The large-$N_c$ masses of light vector, axial, scalar and pseudoscalar mesons
are calculated from QCD spectral sum rules for a particular ansatz
interpolating the radial Regge trajectories. The ansatz includes a linear part
plus exponentially degreasing corrections to the meson masses and residues. The
form of corrections was proposed some time ago from consistency with analytical
structure of Operator Product Expansion of the two-point correlation functions.
Two solutions are found and compared with the experimental data.
