We present analytic expressions to evaluate at O(alpha) the effects of soft-photon emission, and related virtual corrections, in non-leptonic decays type B,D -> P1 P2, where P2 are scalar or pseudoscalar particles. The phenomenological implications these results briefly discussed. For B into charged pions emission quite large: corrections rates can easily exceed 5% level if tight cuts on photon energy applied.
