SRS, a company best known for audio processing used to improve the sound of on-board TV speakers — and one that was recently acquired by movie sound bigwig DTS — has been steadily promoting its Multi-Dimensional Audio (MDA) concept over the past two years, demoing the audio creation/distribution platform to movie studios, music labels, and journalists alike. This spring saw the establishment of version 1.0 of the MDA spec, along with the release of MDA Creator, a plug-in designed for a range of popular audio workstations that enables sound mixers to store audio in the MDA format. Now, the company has added the MDA Director app to its list of new things for 2012.
