R&D Stories: The Arrival of Spatial Room Correction Technology

In this exclusive article for audioXpress, Lars-Johan Brännmark (Chief Scientist, Dirac Research AB) describes an approach to the challenge of applying DSP room correction to complex multichannel setups, intended for immersive audio reproduction. Instead of one filter applied to a single channel, he proposes a solution where all speakers work to optimize the reproduction of each input channel in an optimal way. This article was originally published in audioXpress, December 2021.
