Abstract
A multi-channel signal encoder includes an analysis part with an analysis filter block having a matrix-valued transfer function with at least one non-zero non-diagonal element. The corresponding synthesis part includes a synthesis filter block ( M) having the inverse matrix-valued transfer function. This arrangement reduces both intra-channel redundancy and inter-channel redundancy in linear predictive analysis-by-synthesis signal encoding.
