Abstract (en)
[origin: WO2023280752A1] The invention relates to a computer-assisted method for stable processing of an input audio signal of an acoustic system comprising: at least one audio signal input; at least one audio signal output; a data connection between the audio signal input and the audio signal output, which connection is influenced by an adaptive filter; and an LMS algorithm which controls the adaptive filter; the controlling algorithm being a novel combination of a classic LMS algorithm and a PEAK filter that ensures stable processing of the input audio signal of the acoustic system.
