Abstract:
The present document relates to audio source coding systems. In particular, the present document relates to audio source coding systems which make use of linear prediction in combination with a filterbank. A method for estimating a first sample ( 615 ) of a first subband signal in a first subband of an audio signal is described. The first subband signal of the audio signal is determined using an analysis filterbank ( 612 ) comprising a plurality of analysis filters which provide a plurality of subband signals in a plurality of subbands from the audio signal, respectively. The method comprises determining a model parameter ( 613 ) of a signal model; determining a prediction coefficient to be applied to a previous sample ( 614 ) of a first decoded subband signals derived from the first subband signal, based on the signal model, based on the model parameter ( 613 ) and based on the analysis filterbank ( 612 ); wherein a time slot of the previous sample ( 614 ) is prior to a time slot of the first sample ( 615 ); and determining an estimate of the first sample ( 615 ) by applying the prediction coefficient to the previous sample ( 614 ).

Claim (Index 25):
The method of  claim 17 , wherein the first analytical function determines the first prediction coefficient as a function of a parameter derived from the model parameter.
