Remarques

Par défaut, le bip est lu à une fréquence de 800 hertz pendant une durée de 200 millisecondes.

Beep encapsule un appel à la fonction Beep Windows. La Beep production d’un son sur les versions de Windows antérieures à Windows 7 dépend de la présence d’une puce de minuteur d’intervalle programmable 8254. À compter de Windows 7, cela dépend du périphérique audio par défaut.
