Abstract
A method for processing an input audio signal includes using a first analytical filter bank to divide the input audio signal in a first frequency splitting process into a plurality of first frequency bands. The first frequency bands of a first subgroup are divided in a further frequency splitting process by a further analytical filter bank into a plurality of frequency subbands. The divided input audio signal is frequency-selectively processed or amplified. The divided and processed input audio signal is then combined again into an output audio signal. A prediction is applied to the first frequency bands of the first subgroup and/or the frequency subbands derived therefrom, to compensate for latency differences between the first frequency bands and the frequency subbands as a result of the or each further frequency splitting process. A device or hearing aid for carrying out the method is also provided.
