ABSTRACT:
An audio signal processing device includes a signal supply for supplying coded audio signal over more than one input channel and, per input channel, over separate frequency sub-bands domain sub-channels. Further filters are used to decode and synthesize the audio signals over the total frequency domain. Sub-band combination circuits are used for supplying respective input channels to the same sub-band combination circuit the signals from the same sub-band frequency domain audio signals.
