The goal of spatial audio coding is to data compress multi-channel audio material by combining channels into a composite signal and transmitting supporting side-information so that a decoder can reconstruct an approximation of the original signal from the composite. Many techniques have been discussed in the literature, most of which manipulate across time and frequency the magnitude and phase of the composite channels to create a perceptual approximation of the original multi-channel sound field. Building on this framework, we discuss new techniques for computing and applying the side-information, new de-correlation techniques, and a new way of utilizing a traditional spatial coding system for the purpose of synthesizing a multi-channel signal blindly from an existing stereo signal. We also compare the performance of this system to other existing systems.
