Method and device for selecting a sound algorithm
First Claim
1. Method for the selection of a sound algorithm for the processing of an audio signal, wherein the audio signal is analyzed and, then, based on the analysis, the nature of the audio signal is determined, the audio signal is classified as a music signal or another signal and, depending on the classification, different sound algorithms are used for further processing and later reproduction of the audio signal and, for the classification of the audio signal, the method comprising:
- determining a plurality of different individual quantities (M1 to M6) from at least one of the audio signal and the source of the audio signal (M7),weighting the determined quantities (M1 to M7 differently, anddetermining a total quantity (MG) for the audio signal by classifying the audio signal and by weighted addition of the individual quantities (M1 to M7), andintroducing a hysteresis limit to the resulting quantity so as to avoid frequent switching at a switching threshold when the fluctuations from the switching threshold are small.

Abstract
The invention relates to a method for selecting a sound algorithm for processing an audio signal. The audio signal is analyzed and the type of audio signal is ascertained based on the analysis. The audio signal is classified as a music signal or another signal, and different sound algorithms are used for the further processing and subsequent output of the audio signal.
