An Enhanced SBR Tool for Low-Delay Applications
An established technique to reduce the data rate of an audio coder is Spectral Band Replication (SBR). The standard SBR tool is made for applications where encoding/decoding delay is of no concern. Our goal is to obtain an SBR system with little algorithmic delay for use in realtime applications, such as wireless microphones or video conferencing. We already developed a low delay SBR tool (LD-SBR) but it produces a relatively high amount of side information. This paper presents an enhanced SBR tool for low delay applications which uses techniques from LD-SBR in combination with Codebook Mapping (CBM). This leads to an enhanced low delay SBR tool with a reduced amount of side information but without degrading audio quality.
