| 摘要 |
The present invention relates to an apparatus for processing a plurality of real-valued subband signals comprising a first real-valued subband signal and a second real-valued subband signal to provide at least a complex-valued subband signal with a multiband filter for providing an intermediate real-valued subband signal and a calculator for providing the complex-valued subband signal by combining a real-valued subband signal from the plurality of real-valued subband signals and the intermediate subband signal.
