High-quality Parametric Spatial Audio Coding at Low Bitrates

Recently, so-called binaural cue coding schemes have been introduced. These audio coding schemes transmit two perceptually relevant sound localization cues (i.e., level and time differences between the input channels), combined with a mono audio signal. Although these schemes are able to reconstruct the locations of various sound sources quite effectively, other aspects of the spatial ambience (such as the spatial diffuseness of reverberation) cannot be captured in this way. In this paper, we will present an extension to these spatial coding schemes, which comprises a spatial sound-field parameter that is able to capture ambience properties. Experiments show that the combination of three spatial parameters enables highly efficient, high-quality stereo audio representations.
