The major difference between Dolby Surround Compatible
Downmix and Stereo is that Dolby Surround uses the Dolby
Surround downmixing algorithm and the possibility exists of
connecting an analogue Pro Logic decoder to the sound card so
as to enable 4-ch surround sound (left, right, center, surround)
for Dolby Surround. Otherwise, both are relatively similar in 2-
channel output.
Dolby Headphone is a post-processing effect designed to create
a virtual surround sound experience particularly for a
headphone environment, but is suitable also for both notebook
and desktop environments. For more information, see "Dolby

stadium. For more information, see "TrueTheater Surround
(Headphone Mode) - Optional" on page 93.
