Extract:Meson spectra can provide essential information on low-energy QCD, in particular about the confinement and decay mechanisms. However, the very decay processes, be they real or virtual, may distort the spectra via sizeable and non-uniform mass shifts. Therefore, modern approaches account for quark-antiquark creation and annihilation, as well as S-matrix unitarity and analyticity of mesonic final states. The present talk will thus focus on unitarised quark models and recent lattice results for meson resonances, in confrontation with experiment.
