Restricted Access.Using the multipolar post-Minkowskian and matching formalism, we compute the gravitational wave form of inspiralling compact binaries moving in quasi-circular orbits at the second and a half post-Newtonian (2.5PN) approximation to general relativity. The inputs we use include notably the mass-type quadrupole at the 2.5PN order, the mass octupole and current quadrupole at the 2PN order, the mass 25-pole and current 24-pole at 1PN. The nonlinear hereditary terms come from the monopole–quadrupole multipole interactions or tails, present at the 1.5PN, 2PN and 2.5PN orders, and the quadrupole–quadrupole interaction arising at the 2.5PN level. In particular, the specific effect of nonlinear memory is computed using a simplified model of binary evolution in the past. The 'plus' and 'cross' wave polarizations at the 2.5PN order are obtained in ready-to-use form, extending the 2PN results calculated earlier by Blanchet, Iyer, Will and Wiseman
