TL;DR: In this article, an apparatus for encoding an audio signal comprises the windower (11) for windowing a first block of the audio signal using an analysis window having an aliasing portion and a further portion, and a transformer (13) for converting the processed first subblock and the processed second sub-block from the different domain into a further different domain using the same block transform rule.

TL;DR: All aspects of this standardization effort are outlined, starting with the history and motivation of the MPEG work item, describing all technical features of the final system, and further discussing listening test results and performance numbers which show the advantages of the new system over current state-of-the-art codecs.

TL;DR: An audio decoder comprises a spectral domain decoding branch, an LPC-domain decoding branch and one or more switches for switching between the branches and a common post processing stage for post-processing a time-domain audio signal for obtaining a post-processed audio signal.

TL;DR: In this article, the audio signal is sampled within a first and a second frame of the sequence of frames, the second frame following the first frame, the sampling using information on a pitch contour of the first and the second frames to derive a first sampled representation.

TL;DR: In this article, a short-term and long-term classification of audio and speech segments is performed by extracting at least one shortterm feature from the signal and a shortterm classification result is delivered.
