Abstract:
An apparatus for processing an input audio signal relies on a cascade of filterbanks, the cascade having a synthesis filterbank for synthesizing an audio intermediate signal from the input audio signal, the input audio signal being represented by a plurality of first subband signals generated by an analysis filterbank, wherein a number of filterbank channels of the synthesis filterbank is smaller than a number of channels of the analysis filterbank. The apparatus furthermore has a further analysis filterbank for generating a plurality of second subband signals from the audio intermediate signal, wherein the further analysis filterbank has a number of channels being different from the number of channels of the synthesis filterbank, so that a sampling rate of a subband signal of the plurality of second subband signals is different from a sampling rate of a first subband signal of the plurality of first subband signals.

Claim (Index 15):
Apparatus for processing a time discrete input audio signal, comprising:\n an analysis filterbank comprising a number of analysis filterbank channels, wherein the analysis filterbank is configured for receiving, as an input, the time discrete input audio signal and is configured for filtering the time discrete input audio signal to acquire a plurality of first subband signals; and a synthesis filterbank that receives, as an input, a group of first subband signals of the plurality of first subband signals, and that synthesizes a time discrete audio intermediate signal using the group of first subband signals, where the group of first subband signals comprises a smaller number of subband signals than the number of analysis filterbank channels of the analysis filterbank, wherein the time discrete audio intermediate signal has a bandwidth being smaller than a bandwidth of the time discrete input audio signal, and wherein a sampling rate of the time discrete audio intermediate signal is smaller than a sampling rate of the time discrete input audio signal, wherein at least one of the synthesis filterbank and the analysis filterbank comprises a hardware implementation.
