Using Multichannel Decorrelation for Improved Multichannel Upmixing |
摘要 |
A system of linear equations is used to upmix a number N of audio signals to generate a larger number M of audio signals that are psychoacoustically decorrelated with respect to one another and that can be used to improve the representation of a diffuse sound field. The linear equations are defined by a matrix that specifies a set of vectors in an M dimensional space that are substantially orthogonal to each other. Methods for deriving the system of linear equations are disclosed.
