LX83 LX73 LX53
DTS-HD Master Audio™ and Dolby TrueHD are
the highest quality audio formats available,
provided by the huge-capacity Blu-ray Disc to
complement its high-definition videos. These
new-generation audio codecs bring you the
equivalent of the original soundtrack, just as intended by the
creator.
High Definition Audio Formats
DTS-HD Master Audio and Dolby TrueHD provide sound that is bit-
by-bit identical to the studio master, delivering sound at extremely
high variable bit rates far exceeding standard DVDs.
