Binaural Cue Coding (BCC) offers a compact parametric representation of auditory spatial information such as localization cues inherent in multi-channel audio signals. BCC allows to reconstruct the spatial image given a mono signal and spatial cues that require a very low rate of a few kbit/s. This paper reviews relevant auditory perception phenomena exploited by BCC. The BCC core processing scheme design is discussed from a psychoacoustic point of view. This approach leads to a BCC implementation based on binaural perception models. The audio quality of this implementation is compared with low-complexity FFT-based BCC schemes presented earlier. Furthermore, spatial equalization schemes are introduced to optimize the auditory spatial image of loudspeaker or headphone presentation.
