Patent ID: 8862480

Claim:
Apparatus for encoding an audio signal, comprising: a windower for windowing a first block of the audio signal using an analysis window, the analysis window comprising an aliasing portion, and a further portion; a processor for processing a first sub-block of the audio signal associated with the aliasing portion by transforming the first sub-block into a different domain from a domain, in which the audio signal is, subsequent to windowing the first sub-block to acquire a 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 into the different domain before windowing the second sub-block to acquire a processed second sub-block; and a transformer for converting the processed first sub-block and the processed second sub-block from the different domain into a further domain using a block transform rule to acquire a converted first block, wherein the apparatus is configured for further processing the converted first block using a data compression algorithm.
