Beschreibung
Zusammenfassung:	An apparatus for determining a predetermined characteristic related to an artificial bandwidth limitation processing of an audio signal has a slope evaluator configured for evaluating a slope of a spectrum of the audio signal to obtain a slope evaluation result. The apparatus has a frequency evaluator configured for evaluating a cut-off frequency of the spectrum of the audio signal to obtain a frequency evaluation result, and has a processor for providing an information indicating that the audio signal has the predetermined characteristic dependent on an evaluation of the slope evaluation result and an evaluation of the frequency evaluation result.
