What sort of surround sound support does the PlayStation 3 feature?
For in-game audio, Dolby Digital, Dolby Pro Logic II and DTS are all supported and processed by the Cell. However, keep in mind that since all the audio processing is done by the Cell, developers could use or create whatever audio codecs they desire. 7.1 channel support has already been implemented, but again, given developers’ ability to program their own codecs, this may only be a starting point.
