Une mise en œuvre du procédé consiste à : obtenir un audio à traiter ; déterminer si le dispositif actuel prend ou non en charge l'ajout d'une réverbération audit audio ; en réponse à la détermination du fait que le dispositif actuel prend en charge l'ajout d'une réverbération audit audio, déterminer un algorithme de réverbération selon un type de réverbération sélectionné par un utilisateur ; et traiter ledit audio selon l'algorithme de réverbération déterminé pour obtenir un audio traité. La mise en œuvre met en œuvre une configuration d'activation/désactivation d'un effet de réverbération, permettant ainsi d'éviter un retard évident provoqué par l'ajout de l'effet de réverbération au dispositif ayant des performances médiocres.
