Pro Logic II meets PS2
Dolby unveils new five-channel technology
Published on
Dolby Laboratories launched its Pro Logic II technology for PlayStation 2 from the floor of the GDC, allowing developers to supply five-channel sound as a two-channel stereo audio signal before decoding it using a Dolby Surround Pro Logic II decoder. The report on Al Bawaba (not one of our usual haunts admittedly) claims that the advantages of Pro Logic II in game applications include minimal latency, full frequency range, compatibility with existing cables and backwards compatibility with mono, stereo and legacy Dolby Surround Pro Logic equipment.
