What is Surround for Movies in my Philips SA4TP player?
General information
Surround for movies is an advanced audio technology that directly analyses each sound source in a movie or video soundtrack to re-create a natural soundstage with sound elements that are individually and precisely localized. The processed sound elements are then directly delivered to each ear via in-ear headphones. Surround for movies generates a natural acoustical space based on the actual content of the soundtrack. The result puts the listener right in the middle of the action for an immersive surround experience - just as the film's sound engineer had intended.
