An audio enhancement system and method for use in a surround sound environment creates a more diffuse and continuous sound field from a multi-channel, multi- speaker reproduction environment. Multiple audio source signals generated from an audio recording, which are intended for speakers placed in front of and behind a listener, are isolated into pairs and processed to create corresponding pairs of component audio signals. Each pair of component audio signals is generated, at least in part, from the information present in both corresponding audio source signals. The individual component audio signals are then selectively combined to form enhanced output signals so that each enhanced output signal is modified as function of a plurality of audio source signals.
L'invention porte sur un système amélioré d'écoute utilisable dans un environnement sonore et créant un champ sonore plus diffus et continu à partir d'un environnement de reproduction à plusieurs canaux et plusieurs haut-parleurs. Plusieurs signaux audio sources provenant d'un enregistrement sonore et destinés à des haut-parleurs placés devant et derrière l'auditeur, sont isolés par paires et arrangés pour créer des paires correspondantes de signaux audio constitutifs. Chacune desdites paires est créée au moins en partie à partir d'informations présentes dans les deux signaux sources audio correspondants. Les signaux audio constitutifs séparés sont alors combinés sélectivement pour former des signaux de sortie améliorés dont chacun est modifié en fonction de plusieurs signaux audio sources.
