Title (EN) AUDIO SIGNAL PROCESSING SYSTEM USING A SIGNAL LEVEL GAIN CONTROL ELEMENT
(FR) SYSTEME DE TRAITEMENT DE SIGNAUX AUDIO UTILISANT UN ELEMENT DE COMMANDE DE GAIN DE NIVEAU DE SIGNAL
Abstract: front page image
(EN)Improved audio signal processing system for use in an audio reproduction apparatus. The apparatus is of the type of generating ambient effects and includes at least two channels (22; 34, 36, 38, 40, 42 and 48) for respectively transmitting an audio signal to at least two speakers (24, 26) so that one of the speakers reproduces sound in response to the audio signal at a predetermined delay with respect to the other. The improved system comprises gain control means (42) electrically connected to receive the audio signal being transmitted to the one speaker (26), for controlling the signal gain of the system in accordance with the signal level derivative of the audio signal.
(FR)Un systeme de traitement ameliore de signaux audio est utilise dans un appareil d'audio reproduction. L'appareil est du type a generation d'effets ambiants et comprend au moins deux canaux (22; 34, 36, 38, 40, 42 et 48) pour transmettre respectivement un signal audio a au moins deux haut-parleurs (24, 26) de sorte qu'un des haut-parleurs reproduise un son en reponse au signal audio avec un retard predetermine par rapport a l'autre. Le systeme ameliore comprend des moyens de commande du gain (42) connectes electriquement pour recevoir le signal audio transmis aux haut-parleurs (26), pour commander le gain de signal du systeme en fonction de la derivee du niveau du signal du signal audio.
