AES Convention 119 · Paper 6526 · October 2005

Abstract

The Unified Domain representation for synchronized multi-channel audio streams is introduced. This lossless and invertible transformation describes multiple streams of audio as a single frequency domain magnitude component multiplied by a complex matrix encoding the spatial and phase relationship information for each channel. Unified Domain analysis and signal processing techniques for applications such as high-resolution frequency analysis, sound source separation, spatial psychoacoustic models and low-bitrate audio coding are presented.
