Patent

CA 2376816

A sound switching device is provided with a sampling frequency converting circuit (1) for converting the sampling frequency of an input signal, a delay adjusting circuit (2) for adjusting and outputting the phases of the signal whose sampling frequency is converted and the other input signal, a switching circuit (3) for selecting a signal from the output signals of the delay adjusting circuit according to a control signal. This makes it possible to reduce noise in switching the reproduction of one of different sound signals to that of another signal.

L'invention concerne un dispositif de commutation sonore, comprenant un circuit de conversion de fréquence d'échantillonnage (1) conçu pour convertir la fréquence d'échantillonnage d'un signal d'entrée, un circuit de réglage de retard (2) conçu pour régler et produire en sortie les phases du signal dont la fréquence d'échantillonnage est convertie et de l'autre signal d'entrée, un circuit de commutation (3) conçu pour sélectionner un signal dans les signaux de sortie du circuit de réglage de retard, en fonction d'un signal de commande. Ainsi, il est possible de réduire le bruit par la commutation de la reproduction d'un des différents signaux sonores à celle d'un autre signal obtenu.
