Abstract
An audio matrix decoder is provided for decoding input signals Land Rinto output signals L, C, S, and R. The decoder circuit includes a main signal path having a passive matrix decoder and a cross talk canceller configured to apply variable gain values to intermediate signals and to compute the output signals L, C, S, and R. The decoder also includes a control signal path having a passive matrix decoder and a linear equation solver. The linear equation solver is configured to compute the variable gain values based on the intermediate signals and the necessary condition that re-encoded values of the output signals L, C, S, and Rare equal to the input signals Land R. The linear equation solver is also configured to feed the variable gain values to the cross talk canceller for use in computing the output signals.
