Sound Field Reproduction With Energy Constraint on Loudspeaker Weights
Terence Betlehem, Christopher Stroude Withers · IEEE Transactions on Audio Speech and Language Processing · 2012
Audio rendering problems are not always well-posed. An approach is devised for solving ill-posed sound field reproduction problems using regularization, where the Tikhonov parameter is chosen by upper bounding the summed square of the loudspeaker weights. The method ensures that the sound in the room remains at reasonable levels.
