An enhanced approach to surround sound decoder design

This paper highlights several key improvements that can be made to current surround sound decoder
design techniques. The work focuses on the use of heuristic methods to derive surround sound
decoder parameters for irregular loudspeaker layouts. A comparison is made between decoder
parameters derived from the new improved algorithm and parameters published by others. The
results show that the new parameters derived using this algorithm are superior to other parameters
and the new range removal technique introduced in this paper warrants further investigation.
