Abstract
Linvention concerne une méthode mise en uvre par ordinateur permettant détalonner un signal sonore. La méthode comprend ceci : recevoir un signal sonore initial, un bruit de fond enregistré, un signal sonore initial enregistré et un signal sonore cible; soustraire le bruit de fond enregistré du signal sonore initial enregistré, obtenant ainsi un signal sonore débruité; diviser le signal sonore cible par le signal sonore débruité, obtenant ainsi un facteur de compensation; diviser le signal sonore initial par le facteur de compensation, obtenant ainsi un signal sonore étalonné; et émettre le signal sonore étalonné.
