TL;DR: In this paper, a signal analyzer for analyzing the audio signal is provided, which determines whether an audio portion is effective in the encoder output signal as a first encoded signal from the first encoding branch or as a second encoded message from a second encoding branch.

TL;DR: This new codec forms the basis of the reference model in the ongoing MPEG standardization activity for Unified Speech and Audio Coding, which results in a codec that exhibits consistently high quality for speech, music and mixed audio content.

TL;DR: In this article, a controller is connected for providing the time-varying control signal, which depends on the audio signal, and the controller is introduced to an encoding processor having different encoding algorithms adapted to a specific signal pattern.

TL;DR: All aspects of this standardization eort are outlined, starting with the history and motivation of the MPEG work item, describing all technical features of the nal 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 apparatus for encoding comprises a first domain converter (510), a switchable bypass (50), a second domain Converter (410), a first processor (420) and a second processor (520) to obtain an encoded audio signal having different signal portions represented by coded data in different domains, which have been coded by different coding algorithms as discussed by the authors.
