This signal is often called an Lt/Rt signal. A Dolby Pro Logic decoder will decode an Lt/Rt signal back into four channels. These four channels are: Left, Center, Right, and Surround.
Dolby Pro Logic decoding relies on amplitude and phase differences between the two channels of an Lt/Rt signal to extract the four channels. As a result, there are certain things to keep in mind when mixing in Dolby Surround:
Only one signal can be steered at a time by a Pro Logic decoder. This signal must be the dominant signal. The rest of the mix will be distributed equally among the remaining speakers.
The Surround channel rolls off at frequencies above 7 kHz. You may notice this limited high-end frequency response of the Surround channel in certain situations.
Here are some basic guidelines for using these four channels:
1. If you want to hear exactly what your audience will hear, it is best to monitor and play-test through a decoder.
2. Track and pan the sound of all important objects continually as they move.
3. Although only the dominant signal will be steered by the decoder at any one time, it is still OK to pan multiple signals in different directions. When a signal is no longer dominant, the decoder will find the next dominant signal to steer! Therefore, it's important that all signals are positioned properly even when they are not dominant.
4. The best way to understand how Dolby Surround works is to use it. Practice creating different kinds of mixes. Listen to games and movies in Dolby Surround to gain a greater sense of the possibilities of the medium. You will learn many tricks from careful listening. Finally, do not hesitate to contact us!
Dolby Surround is well established in the game space. There are tools available on all major game platforms for creating interactive Dolby Surround content.
