Title (EN) METHOD AND CIRCUIT FOR CONTROLLING AN OUTPUT OF AN AUDIO SIGNAL OF A BATTERY-POWERED DEVICE
(FR) PROCÉDÉ ET CIRCUIT POUR COMMANDER LA SORTIE D'UN SIGNAL AUDIO D'UN DISPOSITIF ALIMENTÉ PAR BATTERIE
Abstract: front page image
(EN)A method and a control circuit for controlling an output of an audio signal of a battery-powered device are described. The charge condition of the battery is determined and in case of low charge level, the audio filter/gain parameter and/or the audio compression parameter are adjusted to reduce power consumption, thus allowing longer reproducing time by lower sound quality.
(FR)La présente invention concerne un procédé et un circuit de contrôle pour commander la sortie d'un signal audio d'un dispositif alimenté par batterie. La condition de charge de la batterie est déterminée, et en cas de bas niveau de charge, le paramètre filtre/gain audio et/ou le paramètre de compression audio sont ajustés pour réduire la consommation d'énergie, permettant ainsi un temps de reproduction plus long, avec une qualité du son plus faible.
