Claim 0:
1. A method for processing an input audio signal or an input audio signal in a hearing aid, the method comprising:
using a first analytical filter bank to divide the input audio signal into a plurality of first frequency bands in a first frequency splitting process;
using at least one further analytical filter bank to divide a first subgroup of the first frequency bands into a plurality of frequency subbands in at least one further frequency splitting process;
frequency-selectively processing or amplifying the input audio signal divided into the first frequency bands or the frequency subbands;
applying a prediction to at least one of the first frequency bands of the first subgroup or the frequency subbands derived from the first frequency bands of the first subgroup, to compensate for latency differences between the first frequency bands and the frequency subbands as a result of at least one of the frequency splitting processes; and
then recombining the input audio signal, divided into the first frequency bands or the frequency subbands and frequency-selectively processed, into an output audio signal.
