A sound reproduction system comprises an audio source (10) for generating an electronic audio signal which is coupled via a sound processing device (2) to reproducing means (30) which are able and adapted to (re)produce sound in accordance with a reproduction characteristic. Programming means (40) are able and adapted to receive an optionally frequency-dependent pre-correction, this pre-correction being able and adapted to at least partly compensate for a difference between at least one or more parts of the reproduction characteristic and a reference characteristic taken for comparison purposes, and to renew a processing characteristic on the basis of the thus obtained pre-correction. The pre-correction can be accessed separately of the reproducing means.

La présente invention  concerne un système de reproduction sonore comportant une source audio (10) permettant la génération dun signal audio électronique qui est couplé via un dispositif de traitement de sons (20) à des moyens de reproduction (30) qui sont capables et aptes à produire/reproduire un son en fonction dune caractéristique de reproduction. Des moyens de programmation (40) sont capables et aptes à recevoir une précorrection dépendant éventuellement de la fréquence, cette précorrection étant capable et apte à compenser au moins en partie une différence entre au moins une ou des parties de la caractéristique de reproduction et une caractéristique de référence prise pour des besoins de comparaison, et à renouveler une caractéristique de traitement en fonction de la précorrection ainsi obtenue. La précorrection peut être accédée séparément des moyens de reproduction.
