MPEG Spatial Audio Coding / MPEG Surround : Overview and Current Status

Recently, the MPEG Audio standardization group started a new work item on Spatial Audio Coding. This new approach allows for a fully backward compatible representation of multi-channel audio at bit rates that are only slightly higher than common rates currently used for coding of mono / stereo sound. This paper briefly describes the underlying idea and reports on the current status of the MPEG ...

MPEG-4 natural audio coding

MPEG-4 audio represents a new kind of audio coding standard. Unlike its predecessors, MPEG-1 and MPEG-2 high-quality audio coding, and unlike the speech coding standards which have been completed by the ITU-T, it describes not a single or small set of highly e$cient compression schemes but a complete toolbox to do everything from low bit-rate speech coding to high-quality audio coding or music ...

MPEG-4 Audio Lossless Coding

Lossless coding will become the latest extension of the MPEG-4 audio standard. The lossless audio codec of the Technical University of Berlin was chosen as reference model for MPEG-4 Audio Lossless Coding (ALS). The MPEG-4 ALS encoder is based on linear prediction, which enables high compression even with moderate complexity, while the corresponding decoder is straightforward. The paper describ...

Generalized Audio Coding with Mpeg-4 Structured Audio

The MPEG-4 Structured Audio standard was created to enable high-quality, very-low-bitrate transmission of synthetic sound. However, structured-audio techniques also are suitable for flexible natural audio coding. This paper introduces the concept of generalized audio coding, in which the Structured Audio decoder is used to emulate the behavior of other audio decoders. We prove that the MPEG-4 S...
