Binaural Cue Coding Applied to Stereo and Multi-Channel Audio Compression

Binaural Cue Coding (BCC) is an efficient representation for spatial audio that can be applied to stereo and multi-channel audio compression. Conventional mono audio coders are enhanced with BCC for coding of stereo and multi-channel audio signals. There is only a relatively small overhead in bitrate for encoding stereo and multi-channel audio signals compared to the bitrate of the mono audio coder alone. The presented implementations have low complexity and are suitable for real-time applications. Results from subjective tests suggest that the proposed scheme provides better audio quality for encoding of stereo audio signals than conventional perceptual transform audio coders for a wide range of bitrates.
