Title:
PARAMETER ENCODING AND DECODING
Document Type and Number:
WIPO Patent Application WO/2020/249815
Kind Code:
A3
Abstract:
There are disclosed several examples of encoding and decoding technique. In particular, an audio synthesizer (300) for generating a synthesis signal (336, 340, yR) from a downmix signal (246, x), comprises: an input interface (312) for receiving the down mix signal (246, x), the downmix signal (246, x) having a number of downmix channels and side information (228), the side information (228) including channel level and correlation information (314, ξ, χ) of an original signal (212, y), the original signal (212, y) having a number of original channels; and a synthesis processor (404) for generating, according to at least one mixing rule, the synthesis signal (336, 340, yR) using: channel level and correlation information (220, 314, ξ, χ) of the original signal (212, y); and covariance information (Cx) associated with the downmix signal (324, 246, x).
