Spectral Band Replication, a Novel Approach in Audio Coding

Document Thumbnail

Spectral Band Replication (SBR) is a novel technology which significantly improves the compression efficiency of perceptual audio codecs. SBR reconstructs the high frequency components of an audio signal on the receiver side. Thus, it takes the burden of encoding and transmitting high frequency components off the encoder, allowing for a much higher audio quality at low datarates. In December 2001, SBR has been chosen as Reference Model for the MPEG standardization process for bandwidth extension. The paper will highlight the underlying technical ideas and the achievable efficiency improvements. A second focus will be a description of current and future applications of SBR.
