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