Zusammenfassung
Die Verarbeitung, Übertragung, Wandelung und Konservierung von Audiosignalen ist stets mit gewissen Fehlern behaftet, die ab einer bestimmten Höhe den subjektiven Klangeindruck verschlechtern können. Drei wichtige Schlüsselkriterien definieren die Qualität eines Audiosystems: Der Frequenzgang, also die Gleichmäßigkeit, mit der alle in den Audiobereich von 20 Hz bis 20 kHz fallenden Frequenzen reproduziert werden, der Dynamikumfang, welcher das Leistungsverhältnis des höchsten noch unverzerrt übertragbaren Sinus-Signals zum Grundrauschen definiert, und die nichtlinearen Verzerrungen, welche für das Entstehen von neuen, im Originalsignal nicht unbedingt vorhandenen Frequenzen verantwortlich sind.
