Jouez une alerte en diminuant le volume iTunes pendant la lecture.

Bonjour !

Pour la v3.0 de Poker Manager, j'ai introduit une classe qui me permet de diminuer le volume de lecture d'iTunes à  zéro pendant que le logiciel émet une alerte, et qui remonte progressivement le volume à  la fin de l'alerte (comme sur les alertes sur iPhone).

Je me suis dit que ça serait pas mal de partager le truc.
A noter qu'il vous faudra générer le iTunes.h pour utiliser ScriptingBridge (Google est votre ami).

Elle implémente également du code pour utiliser le synthétiseur vocal en tant qu'alerte, je vous laisse faire le tri.
