&daTextBox=<font size="11" face="arial" color="#000000">Dolby Surround encoders accept as input four channels of audio, and output two surround-encoded channels. This is also known as matrix encoding and the output is sometimes called Lt/Rt encoded. The output of a Dolby Surround encoder is stereo compatible, and will play back on any two-channel system. The output can also be sent to a Pro Logic or Pro Logic II decoder, and be rendered back into four channels.
Surround encoded material can be used in any two-channel PC or console game. These games may wear the Dolby Surround logo to encourage gamers to listen to the four-channel audio as intended. Real-time interactive sound effects can be mixed with sound created with a Dolby Surround encoder. For further surround effect, it is highly recommended that real-time interactive sound effects use one of the listed Dolby Surround Interactive Solutions.
