APPARATUS AND METHOD FOR ENCODING/DECODING AN AUDIO SIGNAL USING AN ALIASING SWITCH SCHEME
摘要
An apparatus for encoding an audio signal includes the windower for windowing a first block of the audio signal using an analysis window having an aliasing portion and a further portion. The apparatus furthermore includes a processor for processing the first sub-block of the audio signal associated with the aliasing portion by transforming the sub-block from a domain into a different domain subsequent to windowing the first sub-block to obtain the processed first sub-block, and for processing a second sub-block of the audio signal associated with the further portion by transforming the second sub-block from the domain into the different domain before windowing the second sub-block to obtain a processed second sub-block. Thus, a critically sampled switch between two coding modes can be obtained.
