Abstract

[Engineering Report] The unified-domain representation for synchronized multichannel 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-bit-rate audio coding are presented.
