Abstract

Abstract Translated from German Verfahren zur Übertragung eines digitalen Audiosignals. Erfindungsgemäß wird das Signal vor der Übertragung in ein das Kurzzeit-Spektrum darstellendes Signal (Figure 4) umgewandelt. Für den Hörer irrelevante Anteile des Signales werden weniger gewichtet oder unterdrückt. Dadurch kann der durchschnittliche Entscheidungsgehalt auf etwa 2,5 gesenkt werden. Process for the transmission of a digital audio signal. According to the invention, the signal is converted into a signal representing the short-term spectrum (Figure 4) before transmission. Parts of the signal that are irrelevant to the listener are less weighted or suppressed. As a result, the average decision content can be reduced to around 2.5.
