The Blu-ray release of Michael Bay's supersized 3D actioner has a new surround mix especially for home theaters.
We've been keeping you up to date on the progress of 7.1 in theatrical sound, and Brent Butterworth checked in last month with Dolby Labs Director of Blu-ray Ecosystems Craig Eggers, who gave us an update on some developments in 7.1 for the home — when we talked to Craig, he let us know that while there were some 225 titles available on Blu-ray in 7.1 mixes, most of those simply duplicated the theatrical mixes.
That's starting to change.
