TL;DR: In this article, an audio decoder (100, 300) for providing a decoded audio information on the basis of an encoded audio information (110, 310) comprises an error concealment (130, 380, 500), which is used to conceal a loss of an audio frame following an audio frames encoded in a frequency domain representation (322) using a time domain excitation signal (532).

Patent
Encoder, decoder and method for encoding and decoding audio content using parameters for enhancing a concealment
Jérémie Lecomte,Benjamin Schubert,Michael Schnabel,Dietz Martin +3 more
- 24 Aug 2015
TL;DR: In this article, an encoder for coding speech-like content and/or general audio content, where the encoder is configured to embed, at least in some frames, parameters in a bitstream, which parameters enhance a concealment in case an original frame is lost, corrupted or delayed, is presented.

- 26 May 2013
TL;DR: The proposed Harmonic Spectral Bandwidth Extension (HSBE) method uses arbitrary frequency shifts for modulating the replicated spectrum in a way that the harmonic structure of the signal is preserved.
