Beste Weg, um Sound auf Knopfdruck für einen Java-Rechner zu bekommen?
Ich lerne Java und arbeite an einem unabhängigen Projekt für meinen Lebenslauf. Ich habe mich für einen Java-Rechner entschieden, weil ich die meisten Komponenten kenne, aus denen er besteht. Eine Sache, die ich nicht kann, ist, Ton auf dem Knopfdruck hinzuzufügen. Ich habe eine vage Vorstellung, was mit den Audiostream-Eingabematerialien passiert. Ich benötige jedoch für jede Taste meines Rechners einen eigenen Sound. Im Moment ist mein Rechner noch nicht vollständig fertig (die Hörer funktionieren noch nicht). Ich habe mich nur gefragt, wie ich meine .wav-Dateien am besten in die Tastendrücke einbinden kann. Danke im Voraus.
