SurCode for Dolby Pro Logic II
the best way to encode 5.1 surround for stereo delivery formats.

The SurCode for Dolby Pro Logic II software matrix encoder allows broadcasters, game developers, video producers, and audio professionals everywhere to easily encode 5.1 surround mixes into stereo sound files. Surround ambiences, sound effects, and music stems can all be pre-encoded for delivery within stereo cues, and the resulting mix is completely stereo-compatible.

Dolby Pro Logic II encoding is the world’s fastest-growing matrix surround technology, and can be decoded by virtually every Dolby Digital home theater system sold today. Media encoded with SurCode for Dolby Pro Logic II is backwards compatible with the millions of Dolby Pro Logic receivers and decoders in use worldwide.

SurCode for Dolby Pro Logic II converts your 5.1 surround sound files. to the Dolby Pro Logic II format by matrix-encoding the Centre, Surround, and LFE tracks into the Left and Right tracks. The L and R tracks then become Lt/Rt, which stands for Left total/Right total - meaning that Lt/Rt tracks contain the matrix-encoded Centre, Surround and LFE tracks. These Lt/Rt tracks can be distributed and played in stereo, and also decoded by a Dolby Surround/Pro Logic/Pro Logic II decoder and played back in surround.

SurCode can accept up to 6 master surround sound files. in either .WAV or .AIFF format. SurCode outputs an Lt/Rt .wav file that can be used in any stereo transmission medium.

Audio files encoded by Surcode for Dolby Pro Logic II are fully compatible with all branded Dolby Surround, Pro Logic, and Pro Logic II decoders, either in software or hardware format.

SurCode for Dolby Pro Logic II contains a decoder, which is essential for properly setting the encode parameters. Also, the encoder/decoder in SurCode can work in real-time, enabling you to monitor the results of encoder option changes while making them.

Note:
Dolby Pro Logic II matrix encoding is a creative process, unlike Dolby Digital (AC-3) or other discrete-channel digital data compression (lossy) encoding. Because the matrix encoder combines the Centre, LFE, and surround elements into the Lt/Rt channels by changing level, phase, and other parameters, the channel gain trim settings are quite important in assuring proper stereo and surround compatibility.

When compared to AC-3-encoded sound files., matrix-encoded sound files. are not as discrete in their surround decoding capability; however, Dolby Pro Logic II is the best way to distribute encoded surround mixes or elements within an existing stereo transmission medium, whether broadcast, cable, games, CDs, DVDs, or videotapes. Matrix-encoded sound files. take up no extra space, and use no extra computer CPU resources.
