Patent

CA 2384629

Systems, devices, and methods are provided to inhibit at least one feedback component of an input audio signal by adjusting a feedback-inhibiting filter through a high signal-to-noise subaudible signal. The level of the signal may be determined using an audibility model so as to yield its subaudible quality.

L'invention concerne des systèmes, des dispositifs et des procédés servant à inhiber au moins un composant de rétroaction d'un signal audio d'entrée après adaptation d'un filtre d'inhibition d'effets de boucle par le biais d'un signal infravocal signal/bruit élevé. On peut déterminer le niveau du signal au moyen d'un modèle d'audibilité, de manière à obtenir sa qualité infravocale.
