Remarques
Par défaut, le bip joue à une fréquence de 800 hertz pendant une durée de 200 millisecondes.
Beep encapsule un appel à la fonction Windows Beep. Si Beep produit un son sur des versions de Windows avant que Windows 7 dépend de la présence d’une puce de minuteur d’intervalle programmable 8254. À compter de Windows 7, il dépend de l’appareil audio par défaut.
